My Dear Watson saved our heating/cooling system. We had a wall taken down and there was a return within that wall, and the contractors covered it up and said we did not need it. Over the last 6 months, I’ve noticed our heat and AC were extremely loud and not functioning properly. My Dear Watson is the only company, out of 5 companies (!!) that responded and took me seriously. It ended up that this was our MAIN return! Gordon was a pleasure to figure out the details with and got me on the schedule quickly. Celio did a seamless install and the wooden floor grate actually looks amazing. Thank you so much for all of your help and quick response time. Would highly recommend to anyone looking for a thorough, well done job.

These plumbers were fantastic from start to finish. Before they touched anything, they walked me through exactly what needed to happen: replacing the leaking copper piping and swapping out the old ball valve, explaining why each step was necessary. No vague promises, no surprises.

Everything was clean and professional, and the leak is completely gone.

Highly recommend. Honest, skilled, and dependable. I'll definitely call Dear Watson again for any future plumbing needs.

My Dear Watson has done 5 projects for us over last 18 months. Emergency Location and repair or leaking underfloor radiant heat system pipe repair, with new toilet and sink, vanity faucet repair with excellent results, on time, on budget. This was followed by a very in depth consult for a full gut main bathroom remodel with all new piping, plumbing fixtures, conversion to walk-in ADA compliant shower, framing, electrical, drywall, new mill work, window replacement, tiling shower and floor, painting, on time, on budget, with beautiful results! At this point we felt confident with working with Gordon and his great team to plan, design and move forward with a very large scope multiple room remodel. This included very extensive preliminary design, planing and budget meetings and strategizing living in home during remodel. We were also able to schedule face to face meetings with Gordon’s contractors for preliminary computer design, custom cabinetry and stone countertop selection, early in process. My Dear Watson has a wonderful team of professionals and they were very friendly, respectful of our home, knowledgeable and supportive. The scope of work included: full gut remodel and some removal of non load bearing walls, of kitchen/dining, living rooms to convert to open floor plan, with framing, all new plumbing, electrical, drywall, tile backsplash, custom cabinetry, full appliance package installation, lighting, drywall, millwork, flooring, painting. In 3 bedrooms all flooring, walls, ceilings painted, new millwork installed and windows were replaced, as well as reframing and hanging sliding closet doors in 2 rooms. In addition the guest bathroom received window replacement, new tile flooring, paint, sink vanity install and toilet reinstall. Then that room required then required emergency drywall and reframing as well as replacement drywall, paint and mill work due to a water leak in nearby furnace. Gordon was able to work with our insurance provider to integrate this smoothly into the remodel process even though not in scope of project for fair cost. He also concluded project with additional planned roof inspection and repairs and installation of smoke and CO2 detectors. The only delay was unavoidable when cabinet delivery was late, but other work was done durning this interval. The overall results have been amazing! The entire project results are beautiful. My Dear Watson does high quality work, their team is thorough, meticulous. All inspections were on time and passed fully. The budget was met. It was very large given scope of projects, and age of our home, but was well researched and comparable to the high end of the regional average. Our friends and family have been just amazed at the remodel results and we find all the functional design changes much easier to live with! Thanks again Gordon and you great team at My Dear Watson!

Fast, friendly service. I always know I'm in good hands with My Dear Watson. I had my last water heater installed by them: they did an excellent job, and they even included a rubber water catch basin (first time any installer thought to add that in!). I've had my HVAC serviced by them for years. They're always friendly, they never try to sell me on anything, and they're happy to explain their work. Glad their service range stretches to where I'm at.

Highly recommend. My screened porch needed work. Replace all the trim boards, the screens, new door and paint. Gordon talked me through my options, made recommendations and gavea fair estimate. Celio did all the work and cleaned up the job site really well. The guys are friendly and professional. Quality materials were used. My screened porch looks better than when it was originally installed!
