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!"

"SES is the best company you can think of when it comes to remodeling your house. I finished my project 6 months ago and the communication was great. Maiia from the office kept on following up with every question we had. We had the SES app that we communicated easier and saw pictures of our project throughout the process. 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. Job was done properly, they cleaned the house when they finished and it was a pleasure to do business with them."

"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

Rigid foam board insulation is one of the safest insulation materials for basement walls. The panels offer a moisture barrier to prevent mold and mildew build-up. At the same time, this material is also fire-resistant, so you don’t have to worry as much about a fire breaking out as you would with spray foam insulation. 

You don’t need to staple insulation, as your drywall and studs will hold it into place. But if you already have a staple gun and staples lying around, it can help keep the product in place and avoid any shifting. But, most experts agree it’s an unnecessary step.

If you’re adding a vapor barrier, you will need to staple that in place.

Heavily exceeding building code requirements for insulation not only wastes money on materials but can also lead to ventilation and moisture problems. In most cases, the minimum amount of insulation required by code is perfectly adequate.

Exposed ductwork can sweat just like ductwork placed behind walls, sometimes even more so. Ductwork sweats—like a cold drink on a hot day—because of a temperature imbalance between the air in the duct and the air in the room. In a crawl space or wall, this temperature can equalize faster due to the small space but in lofts and open rooms, that wouldn’t happen as quickly. Many people insulate their ducts for this reason.

Yes, many services include adding insulation for energy efficiency. Confirm with your contractor.
