"There was a problem initially with the radiant barrier installation - the first crew of two were installing 30" wide rolls lengthwise along the roof end to end  instead of from ridge to eave as the manufacturer recommends and made a couple of other minor mistakes which were easily corrected. After talking to the manufacturer, the sales rep offered to take out what had been installed and re-install according to spec or continue as already done with sealing of all seams and a discount on the job. Done this way, the foil would not have the insulation properties per spec but would provide the radiant barrier I desired. I chose the letter option and the barrier work was continued by another crew on the 2nd day. On the 3rd day the crew finished up with the barrier then blew in the installation.

With the exception of the initial problem, the work was done neatly and professionally by courteous workmen who cleaned up completely after the job was done.

Same quality and company, NEW NAME!!!! Yep we've upgraded our branding to better reflect out company goals. As always, quality products are essential for success, but without certified and trained technicians installing everything to the exact specifications for greatest success, your home wouldn't get the best results. That's why we do things right - every time. Our excellent products come with extended/lifetime warranties INCLUDED - there will never be an upcharge for a warranty. The adage "you get what you pay for" is 100% true for Insulation Geniuses. We'd rather explain the investment up front rather than trying to explain quality for the next 20 years...

"Very professional, on time, great communication, thorough examination of my home. This is an absolute requirement for any home owner. The equipment they provide (LED lights, low flow equipment, pipe insulation) is well worth the fee to have the audit conducted."

"The installers were on time and finished in a timely manner. They covered the entire work area with tarp and completely cleaned up when they were done. They walked me through everything they had done and had the permit application with them. They even fixed a minor leak with the hot water duct they discovered while checking the equipment."

"My home was very drafty.  During the consultation I was told that by insulating my heating and AC bills could be reduced by 40%.  This past winter was not cold enough to compare, but in the summer my air ran constantly and my bills were not reduced even 20%.  My interior walls have nail pops everywhere.

Project went very well! I couldn't be more pleased with Timothy's Home Improvement! Two years ago, I contracted another contractor, Tim Powell, to build a shed under my deck. Mr. Powell did a good job but his design did not prevent water from leaking into the shed like he said it would. Many times there would be around 2 inches of standing water on the shed cement floor after a heavy rainfall not to mention all the walls were soaked. Unfortunately, Mr. Powell did NOT return my phone calls requesting he fix all the leaking. After about 6-7 months of chasing after Mr. Powell, I gave up. Fast forwarding to today, the leaking was creating wood rot and serious mold issues. I knew that if I didn't address this issue soon, that the problem would only get worse and cost more to repair. I found Timothy's Home Improvement on Angie's List, and his company had a solid "A" rating. I contacted Timothy Howard, and he met with me within a day or two. We discussed the project and what it would take to repair everything. Timothy's estimate wasn't the lowest and wasn't the highest but in the middle. I decided on Timothy's Home Improvement because of their vast experience waterproofing sheds that are built under decks as part of the deck. During the project, we ran into an unforeseen issue. We would not be able to reuse the composite decking as we had planned. Long story but the original builder used ultra crappy decking material; the deck boards were hollow! And because we couldn't access the screws, we had to tear the boards off which ripped the screws out which left gaping holes where the screws had been. Additionally, the deck boards were too brittle and cracked at the slightest twist. This setback just blew through my $10k budget. Timothy knew I was on a tight budget and did the best he could to keep all the additional costs down to bare-bones like 1) not charging any fee on the materials, 2) passing his contractor prices for material onto you (The contractor price that Timothy pays for materiel is what you'll pay, which is much cheaper than what you'll pay if you go out and buy it yourself including the military discount at Home Depot and Lowe's), and 3) reducing his additional labor cost to install my new deck by $500! Timothy found other ways to reduce costs here and there thus saving me another $550! All said and done, the project came out to around $14k and includes a 3-yrs warranty. The project was finished about 2 weeks ago and took 7 working days. The new deck looks great, and the shed has withstood 3 heavy rain showers superbly?not one single drop of water leaking into the shed!

"They did a great job on the siding.  With the insulation they didn't set it down they kind of laid it on top of some things instead of sitting it down on the joist.  As soon as I called them they came out and gave me an estimate then we scheduled the work.  It was fairly quick.  I would give them an A for the siding and a C for the insulation.  I think the price was reasonable.  For siding I would use them again but for insulation I don't think I would use them again."
