We at Trig Builders offer all inclusive remodeling and construction services for residential and commercial customers. With over a decade of vast project experience all over Los Angeles and Ventura county, we can help you with your remodeling and build your next dream home! 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 could not be happier with the job, would highly recommend!"

"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

The lifespan of cellulose insulation is 20 to 30 years, on average. That said, it’s important to start checking your insulation after year 10 to check for degradation, mold, mildew, and other potential problems. Every 10 years, you should also confirm your home’s insulation is in line with updated local building codes.

When doing any type of project involving mold, it's important to wear the right protective gear. You'll want an N-95 or KN-95 mask to keep yourself from inhaling mold spores, which can be irritating or trigger an allergic reaction in people with weakened immune systems. You'll also want to wear protective eyewear and gloves to limit your contact with mold.

On average, attic insulation costs $1 to $3 per square foot, so for a 1,800-square-foot attic, you’d pay $1,800 to $5,400, including materials and labor. The cost can vary depending on what type of insulation you use, how many insulation layers you need, and whether you need to remove existing insulation first.

If you have bubble wrap lying around the house and you don’t care about the odd look, taping bubble wrap over a window is a very affordable way to insulate it. Another inexpensive option for insulating windows is to add new caulk around the glass. This step quickly cuts down on air drafts for older windows, and a tube of caulk only costs a few dollars. Adding plastic shrink film around the glass is another cost-effective option. You can purchase a kit of plastic film for a few dollars per window.

Depending on where you live and the conditions of your basement, you may not need to insulate your basement. Your best bet is to talk to a basement remodeling company to find out what they recommend doing.

Insulating your basement can help improve your home's energy efficiency, but it will also increase the cost of your basement remodel project. The average cost of installing basement insulation is $2,400.
