Ask This Old House Season 23 proves that home improvement television does not need artificial drama, exploding budgets, or a homeowner pretending to love a chartreuse backsplash. Sometimes the most satisfying story is simply a stubborn gutter, an uneven patio, or an electric bill behaving like it has secretly rented a second house.
Airing across the 2024–2025 television season, the 26-episode run sends Kevin O’Connor and the show’s specialists into real homes, workshops, yards, and communities. The projects range from bathroom accessibility and wooden gutter repair to EV charging, 3D-printed construction, outdoor plumbing, urban gardens, foundation work, and custom mudroom storage. The scope is broad, but the mission remains wonderfully focused: diagnose the problem, explain the reasoning, use the right tools, and leave the homeowner more confident than before.
What Is Ask This Old House Season 23 About?
Ask This Old House differs from the flagship This Old House series in a useful way. Instead of following one major renovation over many episodes, the spin-off addresses smaller, self-contained home improvement questions. The experts make house calls, demonstrate techniques in the workshop, and occasionally visit businesses or community organizations that reveal where building practices are heading.
Season 23 began with “Bath Accessibility; Wooden Gutter Repair” and concluded with “Mudroom Cubbies.” Between those bookends, viewers encounter cracked drywall, smart lighting, rusty bulkheads, ceiling fans, sump pumps, humidifier systems, paver patios, gas fireplaces, bifold doors, retaining walls, mini-split maintenance, irrigation, AC airflow, shellac removal, overseeding, and foundation repair. It is essentially a homeowner’s to-do list after that list has consumed several cups of coffee and developed ambition.
The season also travels beyond familiar New England settings. Stops connected to Miami, Detroit, and Austin broaden the visual and practical vocabulary of the show. Tropical landscaping presents different questions from a northern lawn. A Detroit community garden connects property care with neighborhood renewal. A 3D-printed house in Austin invites viewers to consider how tomorrow’s homes may combine automated wall construction with conventional roofs, windows, utilities, and finishes.
The Experts Who Make the Format Work
The appeal of Season 23 of Ask This Old House depends heavily on its cast. Kevin O’Connor acts as the curious, capable guide who asks the question a viewer is likely thinking. General contractor Tom Silva brings decades of building experience and a calm ability to make complex joinery look almost suspiciously reasonable. Plumbing and heating expert Richard Trethewey explains mechanical systems without turning every pipe into an advanced physics lecture.
Landscape contractor Jenn Nawada handles planting, drainage, site planning, and outdoor design. Electrician Heath Eastman tackles lighting, wiring, energy monitoring, and EV infrastructure. Carpenter Nathan Gilbert focuses on doors, enclosures, cabinets, and other precision projects. Mason Mark McCullough addresses stone, concrete, brick, and water management. Painter Mauro Henrique makes preparationnot merely the final coatthe star of a successful finish. Ross Trethewey explores building science and emerging technology, while Lee Gilliam adds practical lawn and landscape knowledge.
Each expert has a recognizable specialty, yet Season 23 is strongest when several trades overlap. Houses do not respect television categories. An outdoor shower is not merely plumbing; it also needs drainage, enclosure construction, surface planning, and landscaping. A foundation problem may begin with masonry but involve grading and water control. The show repeatedly demonstrates that the best repair is rarely the one that treats only the visible symptom.
Season 23 Episode Highlights
Accessibility That Feels Like Good Design
The premiere’s bathroom accessibility project sets an intelligent tone. Accessible design is not just about reacting to an injury or aging milestone. It can mean planning safer movement, better clearances, secure supports, and fixtures that remain comfortable for a wider range of users. The most useful lesson is that accessibility works best when considered early, before a bathroom becomes an obstacle course with decorative towels.
This approach reflects a larger Season 23 theme: a successful improvement should make everyday life easier. Whether the project is a step stool, stair tread repair, driveway apron, or better closet door, small changes can reduce friction every single day.
Smart Lighting, EV Charging, and Home Energy Monitoring
Season 23 recognizes that modern home improvement increasingly includes software, sensors, and electrical capacity. The smart-lighting segment introduces convenience and control, but the deeper value is energy management. Timers, occupancy controls, dimming, and efficient LEDs can reduce wasted electricity while improving how a room functions.
The EV charger episode is equally practical. Home charging is not simply a matter of hanging a device on the garage wall and congratulating yourself on entering the future. The electrical service, panel capacity, circuit requirements, equipment location, permitting, and installation method all matter. The show’s electrician-led approach reinforces an essential boundary: homeowners can learn how systems work without treating every electrical project as a weekend experiment.
“Electric Bill Investigation” turns an alarming utility bill into a diagnostic exercise. Heath surveys the panel, traces major loads, and installs a home energy monitor. That process offers a valuable model for problem-solving: verify the data, isolate likely causes, measure usage, and resist blaming the refrigerator merely because it looks guilty.
Water Management: The Quiet Hero of Home Repair
Wooden gutters, sump pumps, gutter runoff, humidifiers, retaining walls, foundations, and an outdoor shower may appear unrelated, but all involve controlling water. Season 23 repeatedly shows that moisture belongs where it was intended and becomes expensive when it starts freelancing.
The Cape Cod outdoor shower is a standout example because several trades collaborate. Jenn helps select the site, Mark develops a drainage plan, Nathan installs a cedar enclosure, and Richard handles the water connection and shower hardware. The finished result looks simple, yet the episode emphasizes pitch, drainage material, water movement away from the house, privacy, durable exterior materials, and safe plumbing. That is classic Ask This Old House: reveal the invisible planning beneath the attractive final photograph.
Humidity receives similar attention. Indoor comfort is not achieved by adding or removing moisture blindly. Homeowners must consider climate, HVAC operation, condensation, ventilation, and measured relative humidity. A humidifier can improve a dry winter home, while excess moisture can encourage mold and damage. The season’s practical message is to measure first and adjust second.
Traditional Craft Meets New Construction Technology
One of the season’s most interesting contrasts appears in “3D Printed Homes; Square Bowl.” Ross Trethewey visits an Austin jobsite where a large machine forms concrete walls layer by layer. The technology suggests faster, more automated construction, but the episode does not present it as a magic house printer that spits out a finished bungalow before lunch. Doors, windows, mechanical systems, roofs, finishes, codes, and skilled coordination remain essential.
Then the program returns to the shop, where Tom and Kevin turn a square wooden bowl on a lathe. Placing automated concrete construction beside hands-on woodturning is more than clever programming. It captures the identity of the series: curiosity about innovation without abandoning craftsmanship. Tomorrow’s building industry may use robotics, digital modeling, and new materials, but accuracy, safety, sequencing, and respect for the material still matter.
Landscaping as Infrastructure, Not Decoration
The landscape projects in Season 23 do much more than arrange attractive shrubs. Tree diagnosis, arborvitae removal, irrigation expansion, urban gardening, overseeding, dethatching, aeration, mulch selection, and retaining-wall work all affect drainage, shade, soil health, maintenance, habitat, and property use.
“Beehives 101; Step Stool” expands the idea of a productive yard. Beekeeping is not appropriate for every property or municipality, but learning about hive management and pollinators helps viewers understand the ecological systems around a home. Likewise, the Detroit community features connect landscaping with tool access, food production, education, neighborhood pride, and restoration. A yard can be beautiful, but it can also be useful, resilient, and generous.
The lawn-care segments favor diagnosis over random product application. Dethatching and core aeration address physical conditions that may prevent air, water, and nutrients from reaching roots. Overseeding can improve density when seed selection, timing, soil contact, and watering are handled correctly. The lesson is refreshingly unglamorous: healthy turf often begins below the blades, where nobody can admire it on social media.
Why Season 23 Is Useful for DIY Homeowners
The show does not pretend that every viewer should perform every repair. Instead, it helps homeowners develop judgment. That may be the most valuable DIY skill of all. A person who understands the basic anatomy of a project can communicate better with contractors, compare proposals more intelligently, recognize unsafe shortcuts, and complete suitable tasks with fewer surprises.
It Teaches a Repeatable Diagnostic Process
Many segments follow the same dependable pattern: observe the symptom, inspect related systems, identify the root cause, select a repair, prepare the work area, complete the job, and test the result. That structure applies whether the problem is cracked drywall, poor AC airflow, a loose screw hole, a failing stair tread, or a patio that resembles a miniature mountain range.
It Respects Preparation
Season 23 repeatedly gives preparation the screen time it deserves. Painting wainscoting requires cleaning, sanding, priming, filling, masking, and careful application. Mudroom cubbies need accurate layout and modular construction before the burgundy finish appears. Wallpaper depends on surface condition and alignment. Foundation and masonry repairs require stable underlying conditions. The show understands a truth every experienced craftsperson knows: the final step gets compliments, but the earlier steps prevent complaints.
It Shows When to Call a Professional
Electrical panels, EV charger circuits, gas fireplaces, structural foundations, substantial tree hazards, and complex plumbing can carry serious safety or code implications. Watching an expert is educational; it is not a license issued by the television. Season 23 is most responsible when it explains the system clearly while signaling where licensed, insured, or specialized help belongs.
A Season With Heart: “Thank You, Roger Cook”
Episode 25 pauses the usual repair format to honor Roger Cook, the longtime landscape contractor whose presence helped define both This Old House and Ask This Old House. Cook died in August 2024 at age 70 after an extended illness. The tribute gathers memories of his work ethic, teaching style, generosity, knowledge, and willingness to remain physically involved in the job.
The episode matters because it identifies what makes this franchise endure. Viewers certainly come for techniques, but they stay for trusted people. Roger Cook could explain planting, grading, stonework, or soil preparation in a way that felt direct rather than performative. His legacy is not limited to completed landscapes. It lives in the professionals he mentored, the homeowners he encouraged, and the many viewers who learned to look at a yard as a living system.
Placing this tribute near the season finale gives Season 23 emotional depth without becoming sentimental decoration. It reminds viewers that skilled trades are passed from person to person. Knowledge becomes a legacy only when someone takes the time to teach it.
Where and How to Watch Ask This Old House Season 23
Season 23 originally aired through local PBS stations beginning in September 2024, with availability also promoted through The Roku Channel. Streaming access can change by region, platform, membership status, and licensing window, so viewers should check current PBS listings, the official This Old House site, The Roku Channel, and major digital video services.
The season contains 26 episodes, generally running a little under half an hour. That compact format makes it easy to select an episode by project instead of watching in strict order. Someone planning an EV charger can go directly to the relevant electrical segment; a homeowner battling water near the foundation may prefer the runoff, sump pump, retaining-wall, or outdoor-shower episodes.
Practical Lessons to Carry Into Your Next Project
- Investigate before buying materials. A correct diagnosis is cheaper than three enthusiastic wrong repairs.
- Control water first. Drainage, flashing, ventilation, grading, and humidity management protect everything built around them.
- Match the repair to the house. Materials, climate, age, structure, and previous work all affect the right solution.
- Prepare thoroughly. Cleaning, measuring, protecting surfaces, and planning tool access are part of the job, not delays before the job.
- Know the limits of DIY. Electrical, gas, structural, and major tree work often require qualified professionals and permits.
- Think beyond appearance. The best projects improve safety, maintenance, energy use, accessibility, or daily routines as well as looks.
The Season 23 Experience: What It Feels Like to Use These Lessons at Home
Watching Ask This Old House Season 23 can create a dangerous but productive condition: suddenly noticing everything. The loose bifold door that once seemed “quirky” becomes a repair candidate. The downspout emptying beside the foundation begins to look less charming. The utility bill becomes a document to investigate rather than an envelope to open while whispering, “Please be normal.” The show changes the viewer’s relationship with a house by making its systems visible.
The most realistic way to apply the season’s lessons is to start with one clearly defined annoyance. Suppose a room feels stuffy and the energy bill has risen. Instead of immediately purchasing a new HVAC system, a Season 23–inspired approach begins with observation. Check filters, vents, thermostat behavior, equipment schedules, and obvious air restrictions. Compare current utility usage with earlier periods. Note weather differences. Bring in an HVAC technician or electrician when testing moves beyond safe homeowner territory. Even when the eventual repair is professional, the homeowner arrives with useful information rather than a dramatic shrug.
Outdoor projects benefit from the same patience. Imagine building a small shower near a pool or garden. The exciting part is selecting the enclosure and fixtures; the important part is deciding where the water will go. Walking the site after heavy rain, studying the slope, locating underground utilities, checking local rules, and protecting the foundation may prevent years of soggy regret. Season 23 makes that planning feel less like bureaucracy and more like craftsmanship.
The workshop segments also encourage a healthier attitude toward mistakes. A piece cut too long can often be trimmed. A surface with a poor finish can sometimes be sanded and recoated. A layout error discovered in pencil is merely an inconvenience; discovered after six holes and a bead of construction adhesive, it becomes a family story. Measuring, making test cuts, using scrap material, and rehearsing unfamiliar steps are not signs of insecurity. They are signs that the project may finish before midnight.
Another valuable experience is learning to separate inspiration from imitation. A mudroom cubby design can inspire better entryway storage without being copied dimension for dimension. A tropical fruit landscape that thrives in Miami may be completely wrong for Minnesota, where the mango tree would file a complaint by October. The principlechoose plants for climate, soil, light, mature size, and maintenanceis transferable even when the plant list is not.
Finally, the season encourages viewers to treat tradespeople as knowledge partners rather than emergency buttons. Asking why a repair is recommended, what alternatives exist, how maintenance should be handled, and which warning signs to watch for can turn a service call into an education. That spirit reflects Roger Cook’s legacy and the show’s larger purpose. A well-cared-for home is not a house where nothing ever breaks. It is a house whose occupants pay attention, keep learning, and know when to pick up a tooland when to pick up the phone.
