He recommended exactly what service was needed for us and never tried to "upsale" us on anything. He is a wealth of knowledge and has a very sly sense of humor. I strongly recommend this company and ask for Paul to be your Project Manager. Use this company with zero apprehension. Having an assessment is a very good value in time and money. CONs: Zero!

We first connected with this company at the Home Show. We started with a free inspection. It was…read moreeasy to schedule, and Paul was great to work with. We discussed putting in a whole house fan and the options available. Paul sent along a quote, and while a little high, we opted to move forward. This is the point where things went slightly sideways, and the reason for 4 stars instead of 5. There was an accelerated opening in the schedule that was offered. We accepted and thought the date was locked in. Sadly, the date we thought we agreed on came and went. So, we texted Paul and asked for clarification. Turns out, we were on the schedule for the week agreed on, just a few days later. Paul got everything squared away and things went well from there. Our contractor was Andres. He was on time, kept the dust and mess contained, and when he left, we had a functioning whole house fan, and no sign that any work had been done (clean and fresh paint). Overall, other than some communication challenges, it was a great experience and we're happy with the results.

We quoted our attic air-sealing and insulation job with three companies last summer, and Russell's…read moreexplanation of options and answering of my extensive questions led to us to choose Guardian. Their quote was in-line with the competition as well. Russell has an extensive background doing these jobs himself so he knows what he's talking about. Russell also came over a second time to discuss options for routing our two bath fan exhaust ducts to roof vents when I weighed adding that to our scope. We executed our install over two days in October and everything went smoothly. After air sealing and adding soffit baffling, they blew R30 cellulose over our existing bats. We also added a gasket around our attic access and insulated the back of the panel. My only recommendation is that you, the homeowner, clean your house after the cellulose blowing. There will be fine paper material in the air everywhere, which will settle as dust. Seven months later and our house has been noticeably more temperature stable- warmer over winter and cooler during our recent hot days. Don't skip air-sealing, and make sure to quote with Guardian if you're looking for the best result for your house!

I was planning on painting my house so figured it would be good to insulate the walls from the…read moreoutside before getting them fully painted. After emailing with them I was assured (more like mislead) that the patches done on the exterior walls would be very hard to see and I would be able to just paint them without having to re-patch even though their contract says they just do "rough patches" (email thread image attached). As you can see from the images, the patches were very poorly done and you could easily see the spot where it was patches (raised with a dimple in the middle), which lead me to require having my painters re-do the patches (at my own expense). J & L originally apologized when I told them about the miscommunication and showed them the emails, then they forgot to send me an invoice. A couple months later they re-sent the invoice and when I reminded them about the situation, they claimed 0 responsibility and completely denied any wrong-doing. ( I attached their response email as well) ***** If you feel comfortable working with a company that will throw you under the bus instead of admitting a mistake, then this is the company for you! ***** tl;dr Their contract explicitly states that their patches will be bad and you will need to have them redone, then when I asked about that part of the contract they explicitly told me the patches would not be visible.

And somehow no one has ever put insulation in our home since it was built in 1938. I saw another reviewer contacted him about the same thing and had a good experience even though it's not really in this business's current scope of work. I had the same great experience. Spencer looks at the big picture, unlike individual contractors who handle a single facet of a project like this.You can tell he's passionate about energy efficiency and helping people make their homes more comfortable. He also knows what he's talking about and is knowledgeable about products and local contractors/vendors. After our conversation, I was more educated about the variables involved with making our project work. There was no sales pressure, but we are going to have Spencer review whether a solar system is right for our home. If you're considering a project to make your home more energy efficient, I highly recommend calling Energy Integrity.

We had thought about getting the job done for months before we pulled the trigger. Spencer was great at keeping in touch with absolutely no pressure. Once work began, his team was quick and clean - you wouldn't have even known they had been there. Now that the summer is starting to heat up, I'm so glad we got the work done. We've quickly developed a routine of coming home, opening specific windows and running the fan. Then at dinnertime, we switch up the windows and cool different parts of the house. It's to the point where I'm actually cold at night, despite the high temps all day! That never used to happen! Bottom line - great communication and high quality work!

The estimate is very detailed as to the process and when the staff found some additional rotted wood under the original roofing material, it was replaced without any extra charges. How often do you find that these days?! Mike Runyon is the project manager and his staff (Chico) were very professional, courteous, had great communication skills, and there was never a mess during or after the job. They also showed up on time every day. If you are thinking about redoing a flat roof "Spray Foam Roofing" is the answer. HIGHLY RECOMMEND!! :-)
