"Great quality work, paid attention to every detail; from laying down plastic to corner guards to cleaning up every last piece of insulation on the ground outside. The owner and his crew, who were his father and family friends were very professional and kind. The best owner and operator business that I would recommend to the next person in line."

"Technician Jake Sheiner came out for free inspection and estimate. Explained with the amount of blown-in insulation we already have that adding more would not net any energy savings. He was honest, polite and knowledgeable and did not try to see us something we did not need. He cleaned up after inspecting both attics and explained everything he found to us. Thanks, Jake."

"We have a 1970's and we decided to have an energy audit by Landmark Construction. It was clear that our house have some energy issues and was in need of a any type of energy overhaul.  The report that was prepared for us by Charlie and his office staff, was comprehensive, clear to understand and revealed that the ducts at the attic  was not sized appropriately. In addition to that, the furnace/AC in the smaller unit was old (and original) and had to be replaced. The recommendations that Charlie told us, included a new furnace/AC, new tankless water system, hot water pipe insulation, building sealing, the insulation and new ducting throughout the house. This was the best investment we ever made.  I could not believe the difference in our utilities bill.  Charlie and his team were great,  professional and experienced. I wish we did these 15 years ago!!

"Finally an honest Solar company!! I went through several companies trying to get quotes for one of my properties, either they were ridiculously expensive or they didn't return my calls. A friend of mine referred me to Mega Sun and I have to say I am very pleased. Within a couple days from the initial phone call I already had an estimate and once i decided to go with them the installation was completed in one week. Its been a little over a month since they completed the install and everything is working smoothly.

I was amazed at just how great the customer service was. I just want to say thank you to the whole team who helped out, I really appreciate all your hard work. Now I know you guys are the ones to call for all future jobs."

"After we returned home from our summer vacation out of town, we found that our master bath and bedroom had flooded due to rain and clogged plumbing. When I called the chief executor of Hometown Restoration, he replied quickly, provided a reasonable quotation, and started work straight away. We were delighted with the accuracy of the treatment of water, as well as the quickness through which his workers restored our master suite after insulation removal, flood cutting, and so on. Our home looked nicer than the original! Staff were professional, kind, and meticulous in their clean-up. I would refer Hometown Restoration to others!"

"I bought an Angie's list deal for dry wall repair but really they just spread some spackle on it and left it rough. I had to scrape off the blobs of spackle left on the ceiling. My boyfriend could have done the same job. I wanted them to actually replace the dry wall where it was cracking. Mainly they wanted to sell me more jobs and pushed me to sign on with them to get new insulation in the attic. I had them give me an estimate on rain gutters while they were here. Their estimate/prices are very high. I think they have to pay for all those people manning the phones. It sounds like a boiler room when they call."

Insulation questions, answered by experts

A vapor barrier keeps moisture out of the crawl space, while insulation reduces the amount of unconditioned air—and sometimes moisture—that enters the space. Coupling a vapor barrier with insulation can help prevent humidity and related moisture damage in a crawl space while also making your home more energy-efficient. Just be sure to use insulation that won’t get damaged from moisture, like rigid foam board or expanding spray foam insulation.

Energy-efficient homes generally have higher appraisals and appeal to buyers.

These two types of foams are similar chemically, but they are applied in a much different way and each has its own pros and cons. Spray foam can only be used if the area where you will be installing the installation is wide open and easy to access. Injection foam should be used where it's cost-prohibitive to remove the walls that are placed over the insulation. Spray foam is a much less expensive process and requires less expertise. 

Insulating your basement walls offers numerous advantages that make the project well worth it. By adding insulation, you can reduce the chances of moisture damage to the house's structure and lower the odds of mold growth. You'll also add comfort to the space by reducing temperature swings and increasing your home's energy efficiency, potentially reducing your energy bills to earn your investment back.

The best time to insulate a garage ceiling is when the weather is mild and dry. That means it shouldn’t be stormy, snowy, or raining, and the temperatures should be comfortable. Ideally, you’ll insulate your garage ceiling in the fall, before winter hits. Not only will you be the most comfortable, but you’ll also likely see the greatest energy savings heading into the colder weather with a newly insulated garage.
