  • We had multiple bids to to install blown in insulation for the exterior walls of our house and bring the attic up to current standards as the minimal amount of insulation was making the house feel a bit like a cabin during the winter and overheated in the summer.  I was impressed with the bid Provider name locked. provided us as they were the only ones to actually spend time up in the attic beyond just a look around through the access hatch and call out that the vent ducts for the bathroom fans were not installed properly (prior owner had been running them through dryer hose vs. directly up and out the roof) and that the insulation shield around the chimney wasn't present which we had known from having gas fireplaces installed last year.  Additionally they were the only ones that took the time to verify that there wasn't actually any existing insulation in the outside walls.  We were pretty sure based on input from neighbors but appreciated the thorough inspection of both the attic and walls before generating a quote.  Further they took a very careful look around the exterior walls and in the process pointed out a couple minor non-related maintenance items to address as DIY type projects that fall outside their scope of services.
    Scheduling was easy and they were also able to accommodate an extremely last minute request to arrive a bit earlier than had been agreed upon due to a last minute appointment that came up.
    The crew arrived even earlier than requested and did a great job explaining they work to be done again then got right to it.  They took great care to protect our floors indoors and worked around all the landscaping outside.  They were very fast, efficient and the quality of work in closing up and sealing off the holes drilled outside to blow in the insulation was great.  We just had to do a little sanding, prime and paint and everything is good as new.
    Upon completion (several hours faster than estimated) they did a thorough clean up job, showed us everything they had done. Madrona determined that the estimate which had been very much in line with others we received for this work was actually a bit higher than it should have been so this great service all the way through the process turned out to cost less than we thought.  
    Will definitely use Madrona again in the future if the need arises.

  • Incredibly poor quality of work, they split the drywall in my walls in three locations, soffit vents had crude scratches around them as if they were marking where to cut with a screwdriver, attic hatch weatherizing was poorly completed, they didn't adequately caulk the siding they removed and did a poor job replacing the siding they did remove.
    The owner was insistent that their poor quality of work was the result of my house being old, which is complete garbage.  I had another contractor come through and verify that the quality of work was awful.  To their credit they sent out a carpenter after many back and forth emails with the owner and he was able to fix some of the problems, however I would not go with them again for anything.

  • Provider name locked. from Provider name locked. was excellent. Very informed and up to date in insulation and condensation technology. I have an old small craftsman that has the attic converted to living space. 2x4 roof rafters leaving minimal area for insulation and no area for air space above. After several quotes from less informed insulation contractors I learned of AT. Provider name locked. confirmed my concerns and more fully explained how to approach the problem. We ended up with a combination of closed cell foam in the living spaces and open cell in the non -living areas to achieve a decent R value. The cost was very fair. The team arrived on schedule, got right to it and finished timely. Veteran owned and operated. There was a lot of prep but the outcome should be worth it. Highly recommend these guys. Easy to communicate with.
