I have over 30 years experience in my trade, in business for over 20 of those years. Check are accepted. Time and material is available as well. 1099's accepted for tax purposes. I have insurance up to $1,000,000 for property damage. Lic # C-35480

"We needed some drywall work done and H Drywall was one of three companies I contacted for estimates. They were the middle bidder, but I was so impressed with Harry’s (the”H” in H Drywall) on-site visit and his comprehensive proposal that I decided to go with them. I was not disappointed because Harry keeps on top of things and is quick to reply to messages. A bonus was their online payment system which is really convenient and provided instant confirmation of a payment. What truly makes this company worthy of a 5-star rating though are its employees. John, the foreman, is easy to talk to and has so much experience in construction that he solved any problems or challenges that occurred. He always kept us informed of their progress and made sure we were happy with the work they were doing. The rest of the crew Stuart, Derek, Chris, and Evan were all friendly, courteous (always aware that we still lived in the home), and did excellent work. Drywall replacement is messy, but these guys covered everything including the floors and they vacumed daily. The drywall removal uncovered some additional work that needed to be done and H Drywall provided a reasonable estimate to fix the problem. We also had them paint the living room, dining room, and kitchen areas. Thank you Evan for helping us choose the right color! This company, and I mean the whole company, definitely deserves a 5-star rating."

Insulation questions, answered by experts

Asbestos has many beneficial properties, including fire resistance, strength, and chemical resistance. It is also an excellent insulator, which is why it was used in pipe insulation and other building materials for decades. For all its benefits, asbestos is dangerous for human health, which is why it was eventually banned from use in certain products.

2x4 walls can hold R-13 or R-15 batts of insulation, which is usually about 3.5 inches thick. You should also check with your local building codes to see if there’s a required thickness you need to adhere to. 

You can also use R-value maps to determine the best thickness and ratings for where you live. For example, someone in Texas doesn’t need as thick of insulation as someone in Montana. Energy Star has a good one you can reference.

It is possible to insulate your walls without removing drywall, but it’s not a good idea to attempt the work yourself. A professional can use blown-in insulation or spray foam insulation to fill wall voids without opening up the walls, and the option they use typically depends on your climate and whether or not there’s insulation in your wall already that can remain in place. Spray foam insulation costs more and isn’t always a viable option, but it’s a better insulator. Call in an expert to help decide which is right for you.

Just how long insulation lasts depends on the type of insulation you use. Fiberglass can last between 80 and 100 years, but it's important to start checking fiberglass insulation around the 15-year mark. Spray foam also has a long life span of up to 80 years, while mineral wool can last up to 100 years. Although eco-friendly, cellulose only has a lifespan of 20 to 30 years.

Although the cost might seem high, winterizing your home is important for your health and the structural integrity of your home. Winterizing will keep your home warm and toasty during the cold months and prolong the life of your appliances, windows, pipes, sprinkler system, pool, and more.
