We are general contractors, but we also provide the following services: roofing, room additions, kitchen remodeling, bathroom remodeling, windows and doors and so much more.

"Buyer beware!!! I have never had such a nightmare with this company. Save your money and your sanity. They installed a patio cover for me. It leaked immediately. This was two years ago. For the past two years, they have been out at least 7 or 8 times claiming to "fix" the leaks. The leaks were not normal patio leaks by the way. The leaking has cause 3 of the 4 lights installed in the patio to fail. Every time they come, it's never fixed. The leaks keep getting worse. They never follow up with me, I always have to call them. They do not manage their sub contractors at all. This latest round started just before Christmas 2021, it's now been three months, four visits later. They took flashing off, said they were going to let it dry out and put it back. I didn't hear from them for two weeks, I noticed rain on the weather , I called Trig who had to send them back out to put the flashing back on. They sent some guy to do some more drastic sealing or something on my roof, they claimed it was done.....see attached photos of how they left my roof claiming it was done. Also, never followed back up with me on a light they need to replace which is still burned out and filled with water from rains. Save yourself the headache please!!! This still isn't resolved. I have filed a BBB compliant to try and help me resolve."

"We used Ivy Builders to remodel a 30 year-old bathroom in our 60 year-old house. Nathan and crew were outstanding. The job was on schedule and on budget. Every hiccup, bump and oversight were handled without drama. Nathan knows his business and as he told me one day, "You just plan for there to be problems and you handle it, happens on every project." We could not be happier with the job, would highly recommend!"

We live half of the year in Russia and due to COVID we couldn't come back so it took a while until we were able to see how it came out.

"We hired Four Seasons Remodeling and Design to replace a large deck at our home, and the results exceeded our expectations. They removed the old deck, installed new caissons for proper support, and rebuilt everything from the ground up. The crew was knowledgeable, organized, and respectful of our property. The final product is sturdy, well-built, and looks fantastic. I would definitely use them again for future projects."

Insulation questions, answered by experts

A radiant barrier is worth the money if you live in a hot, sunny climate. Over time, you should be able to recoup your investment through lower energy bills. Though it can vary depending on where you live and the type of barrier you choose, you might be able to reduce your electric bill by as much as 5% to 10% after installing a radiant barrier.

While you should always insulate ceilings and exterior walls, you don’t always have to insulate the interior walls of your home to maintain energy efficiency. However, there are benefits to insulating every wall, including improved soundproofing and energy efficiency throughout your home.

Water freezes at 32 degrees Fahrenheit, but the actual temperature that can cause frozen pipes can vary. Generally, it takes 12 hours for pipes to freeze at 32 degrees Fahrenheit.

Uninsulated pipes can freeze if it’s 20 degrees Fahrenheit or colder for over three hours. If your pipes are insulated, it can take six hours or longer for pipes to freeze. Note that some pipe types freeze more often than PEX pipes. Copper pipes freeze more often because the copper conducts energy and loses heat quickly.

Even though spray foam insulation typically comes at a higher price point than other insulation types, the benefits make up for the investment. Some benefits of spray foam insulation include:

  • Improved air quality, as this type of insulation helps minimize indoor allergens

  • Easy installation 

  • Lifespan of 80 to 100 years.

  • Added home strength, protecting it from humidity and wind.

  • Additional soundproofing

  • Energy bill savings

Reflective and high R-value batt or roll insulation are often considered energy-efficient, offering significant thermal resistance benefits.
