"We contacted Mr Groves and scheduled an estimate consultation, he didn't show up for this appointment and I had to call him to reschedule. 30 minutes after he came to our house and gave us an estimate he called me to say he was running late, I reminded him that he had just been there. He said that the coupons on this site were no longer valid. We signed the contract for roof and gutter replacement and schedule a date for the roof to be replaced. A week before our scheduled roofing Mr. Groves called e to say that he would be out to give me an estimate for our roof. I called him back and reminded him that he already had and that we were scheduled for the roof to be replaced, he assured me that he would be there on the scheduled day. His crew showed up and did a great job on the roof. We asked when the gutters would be done and were told in a few days. We explained that we needed to know when the work would be done as we have two big dogs and needed to be home to keep them inside while the work was being done. I had to contact the company again a week later to ask when the work would be done, was told that they would return my call and let me know. I had to call back the next day and was told that the gutter guy hadn't given them a day yet but that they would let me know prior to the work being done. A week after that men showed up in my driveway, fortunately I was off but had planned on going out that day. I had to cancel my plans and stay home to keep my dogs inside. The downspouts were not placed where y husband wanted and he had discussed this with Mr. Groves when he gave us our estimate. The gutters are black but you can see white on them so we will have to paint them. I contacted Mr. Groves to let him know that we were not happy with the job, he said he would talk to his project manager and get back with me. 2 weeks have passed and still no word back from him. I paid him for the work but would not recommend him to anyone else. Obviously he doesn't care that the work was ot done to our specifications nor that we are unhappy with the job."

Insulation questions, answered by experts

Expect your home insulation project to take between five and 12 hours to complete on average for batts or boards and two to five hours for spray foam or blown-in insulation. It might take longer if you need to remove your home’s existing insulation, you have a higher-than-average square footage, or accessibility is limited.

Ductwork sweats for the same reason you might find beading on your windows or why cold drinks drip in the heat—temperature difference. When you see your ductwork and you notice sweating, that's a sure sign that your system is not operating anywhere close to peak efficiency. The best way to keep ductwork from sweating is to wrap it in inadequate insulation.

Insulating windows without plastic is usually the better method. Outside of simply replacing your windows, you could buy cellular shades, which trap air between the window and the home, add a window film that blocks UV rays and traps heat, or cover your windows with a low-emissivity coating called “low-E.”

Yes, brick houses are better insulated, because the bricks slow down the passage of air from the outside to the inside and vice-versa. This helps to stabilize the internal temperature of the home. When combined with proper residential insulation, brick houses are more efficient and better insulated than other types.

R-30 insulation is better for higher thermal resistance, but whether it’s "better" depends on the application. R-30 is much thicker and suited for areas like attics or floors in cold climates, where more insulation is required. R-13, on the other hand, is thinner and works well for 2x4 walls or milder climates where less insulation is sufficient. Choosing between R-13 and R-30 depends on the area being insulated and the climate. For example, R-30 provides more insulation but may not fit everywhere in your home.
