"I have hired Permaseal to fix my unleveled patio concrete floor that was and still causing rain water to get to my basement, I have paid them $2,014.33 as down payment, they showed up one month later for the job, which is injecting foam under the concrete slab to lift it back to its original correct level. I came back home that day to find out that they have left and that the concrete slab was not only still unleveled, but they cracked it and patched it on multiple locations. I have called their customer care number more than a dozen times in attempt to understand what is going on, and on each occasion, I was told that the project manager was going to contact me back, which never happened until i made the next call, They have finally explained to me over the phone that it was the best they could do and that they could not fix my patio floor. I asked for a refund and did not hear back. I have documented pictures of before and after showing that the job was not done and cancelled the check with the remaining balance. I have not heard anything back from them since then, until i started getting debt collectors' emails on December the 5th from a business called FCR Services."

"We reached out to Dan with the issue of freezing pipes and cold rooms in our old house. Dan inspected the house and proposed a plan to remedy these issues. Aside from the more traditional air sealing and insulation solutions, Dan also recommended insulating the area of our house above our soffit, which was difficult to access but that appeared to be a major insulation issue. I should add the other firms we requested quotes for did not identify this area in their proposal. I firmly believe the proposals from the other firms would not have fixed our issues. Dan worked for ~2 weeks on air sealing our attic and house, adding insulation to our attic, removing our soffit and adding insulation and reinstalling soffit. Work was done well and within budget and at a fair price. Dan is very easy to work with and takes pride in his work. We are very happy to report our pipes have not frozen and the cold rooms are no longer cold - would highly recommend Dan to others - he went above and beyond."

"The plumbers this company sent to my house did not put the washing machine drain hose back in the drain. We did laundry and flooded the kitchen and damaged some wood flooring. Contacted this company and they said it's on the plumber to fix it. I don't have plumber contacts. They said they would help me get it fixed and did ok at first. It's been over 6 weeks later and no one has done anything. Nothing has been fixed. Everyone has said, including the plumber, this was not our fault, yet no one will fix it! I've asked even for a refund so I can get the floors fixed and again, nothing. This is the company we hired and they just pass the buck. They are not helpful but nice so try to give you hope things will be ok. It's a joke, poor customer care and I will NEVER use them again and wish I could have called around instead of using Home Depots suggestions. "

Energy Efficiency Auditing questions, answered by experts

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.

If your AC runs constantly, it could be due to a number of things, including a faulty thermostat, incorrect temperature settings, or broken equipment. Alternatively, you might have an airflow problem (for example, blocked vents or leaky ductwork). Either way, an HVAC pro can identify the specific problem and fix it for you.

R-value is calculated by dividing the thickness of an insulation material by its thermal conductivity. The material's composition and density influence thermal conductivity. Materials with lower conductivity values provide better insulation. The higher the R-value, the better the material is at insulating, helping homeowners select insulation that meets the energy needs of their climate and home layout.

Absolutely! Especially if you have an older home that currently doesn’t have air conditioning where installing ductwork just wouldn't work. No one likes being hot in the warmer months, so if you’re looking to sell your home in the near future, installing a ductless mini-split AC can be a good way to enjoy your home more while you’re in it, boost the return on your sale, and serve as a perk to peak buyers’ interest.

Audits include inspecting insulation, HVAC systems, windows, and appliances to identify energy inefficiencies.
