"From estimate to job completion, very satisfied with the professionalism demonstrated by this company. The job was completed with the installers arriving on time. I appreciated the fact that they wanted to leave my home and walls clean of scuff marks that could be caused by their equipment. Good job and thanks!"

"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."

"We needed a new roof for our house. Our ‘old’ roof had few leaks and several problems that required the replacement with a new one. The last rain resulted in a water leak to the bedrooms area. So, we called Landmark construction energy upgrade because they did our neighbor's roof a year ago and they gave us an estimate at that time. This time, they just updated the estimate and they were able to lower it, which was cheaper than the other estimates we got. The good feeling was much better because it’s a family business who not only give the bid but do the work. No hard sell here or having the bid from one guy but the work is with unknown others - as it was with other bids. Landmark did the job so good and very fast as well which was awesome! The workers from Landmark made sure to clean the roof and they did a quality work. The roof was a mess with lots of humps, bumps and terrible pad for the Air conditioning. They rebuilt it all, and had people who came to do specialty tasks, such as hooking up the dish, the air conditioning condenser etc.… More than that, they also fixed the gutters and made sure they are connected correctly. All in all, this project is complete and done. We are no longer have to deal with the old roof and leaks for at least for 20 years. Before we did the new roof, The office staff helped us with the Cool Roof rebate from the power company and the federal tax rebate for an Energy Star roof, both of which we were not aware. Landmark construction energy upgrade are now our roofers who did a great work and have other great contractors to supplement for special tasks and run an all-around energy efficient business. If we ever move or we have a natural disaster, we know who will work for us."

"we were very impressed with out solar endeavor. The installers came when they said they would and finished their job within the same day. We added insulation to our attic to reduce our heating and cooling for the house and replaced 2 old windows . All the guys were great from Idan who evaluated our home, office staff and installers. We are very happy. "

"AHS is ok. They cover repairs of most everything under the roof of your house. The companies that contract with them are not always the best. You call AHS with the issue, they send a fax to the repair company and give you the contact info. If they don't contact you within 24 hours, you call them. Sometimes they answer, sometimes they don't. When they arrive (usually three days or so later), they service the item. if it has issues within the 90 days, you call AHS again, they are sent out with no charge. If the serviceman decides the unit is unrepairable, AHS will allow you to choose a replacement from their listing (usually not as good as what you have) they will install and remove your old item, or give you wholesale amount to buy and install your own. Prices vary on what you want covered and what you want the copay to be, plus where you live. For me it is 49.99 per month with a 75.00 time of service order. You can have more than one item serviced at the same time under the same fee. If you have a SEAR product the repair guys are great. Not that wild about the other ones they send out. But it is a big savings compared to calling someone on your own. The cost of service is only the 75.00 copay."

FAQs for batt, rolled or reflective insulation install or upgrade projects in Guerneville, CA

Batt insulation excels in vertical installations because it remains firmly in place and delivers consistent thermal performance. Blown-in insulation performs exceptionally in spaces such as attics, efficiently filling gaps in irregular areas. 

Employing both insulation types according to their strengths enhances your home’s overall energy efficiency and comfort by providing a tailored solution for every space.

Start by measuring the square footage of the space, then match that area with the insulation thickness you need to hit your target R-value. Add a buffer for waste and odd-shaped spots so every cavity is covered. 

Once you have a rough count, run it past a local insulation pro—their on-site advice will fine-tune the numbers and help you avoid costly miscalculations.

Old insulation that is dry, intact, and mold-free does not require removal before adding new insulation; stacking new insulation over it maintains effective thermal performance and boosts energy efficiency. 

If the insulation is damp, moldy, or deteriorated, removal is necessary to eliminate health risks and ensure maximum effectiveness of the new layer. A professional insulation contractor will assess your situation and recommend the most effective solution.

Installing insulation in an average-sized home using batts or boards requires five to 12 hours. Using spray foam or blown-in insulation requires two to five hours. These timeframes are determined by the area’s size, accessibility, and whether old insulation must be removed. 

Complex projects and hard-to-reach spaces demand extra time. Hiring an experienced insulation professional ensures that the installation is completed efficiently and correctly.

Insulation is measured by R-value, which defines how effectively it resists heat flow. A higher R-value provides superior thermal resistance, ensuring your home remains warm in winter and cool in summer. 

Choosing the correct R-value is essential for maximizing energy efficiency and comfort, and it directly impacts long-term utility savings. Professional guidance determines the optimal R-value for your specific climate.
