    Chris and his team were awesome to work with. They removed the old, bad insulation from my attic,…read morecleaned everything out, and cleared a surprising amount of debris I didn't even know was up there. The space looked completely refreshed afterward! About a month later, I had them come back to add new insulation and handle the air sealing. Same experience -- fast, solid workmanship, and a very reasonable price. Overall, really smooth process and great results. I'd definitely recommend Chris's Insulation Services!

The day of, whoever we were confirming with wasn't sure what the job was, which should have been our first clue things were going downhill. We have a baby and we have to plan everything around naps, so i said we we were free from 10-12. They said they would be here at 12 and the cleaning would take 25 min which was pushing it for us with a 12:30 nap. 12 came and nobody arrived. I texted asking if they were coming, nothing. I reached out to communicate that they were so late, we can't do it anymore, and asked for availability for next week. Nothing. Half an hour passes and I finally get the baby down for a nap and the DOORBELL RINGS. We have a huge sign on the door that says "do not ring the doorbell -baby is sleeping." I think it can't possibly be the cleaning guy, I already texted him and the sign clearly says don't ring. I finally get the baby back settled, he rings the doorbell another THREE TIMES. I'm absolutely livid, the baby is crying, the dog is barking, and the guy on the porch has the audacity to say he hit traffic and still wants me to let him do the job. Incredulous. Terrible communication, terrible responsiveness, and I have no idea how the work would have been, but after that experience, I'm absolutely not going to give them another chance at rescheduling. My whole day is off the rails with an agitated, overly tired baby, and my dryer line job is still not done. What a mess.

    I recently had a Mitsubishi heat pump system installed along with full air duct replacement by…read moreElement Home Solutions, and I couldn't be happier with the entire experience. From the very beginning, the estimate process was smooth, clear, and professional. They took the time to explain my options and helped me choose the right Mitsubishi system for my home without any pressure. The installation itself was efficient and well-organized. The crew showed up on time, kept everything clean, and completed both the heat pump install and duct replacement with great attention to detail. You can tell they really know what they're doing. What really stood out was how seamless the whole process was--from the initial estimate all the way through permits and final inspection. Everything was handled properly, and I didn't have to stress about any part of it. Overall, a very professional and reliable team. I highly recommend Element Home Solutions if you're considering a heat pump or ductwork upgrade.

They tries selling us a ridiculously expensive duel fuel system and a bunch of other extras we didn't need. Cesar came over from Element and was the first and only of the 5 or so companies I had give a bid that was honest and directed me towards a all electric heat pump system. After doing a lot of research we came to the decision to go with Element. They replaced our whole system, new ducting, zoned the system, and removed the old insulation in the attic, sealed everything, and installed new insulation with our new HVAC System. I was very please with the professionalism, communication, and overall work performance of Element and the crew. Cesar was at the project the whole time which I very much appreciated. He isn't just the person who puts together bids, he was up in the attic helping the crew complete the job. That was a nice surprise and much appreciated. I would definitely recommend them and will most likely used them in the future to insulate our crawlspace.

    I had a fridge in the basement where I kept my work items and all of a sudden it broke down because…read morethe mouse chewed the cables and broke the compressor so I had to buy a new fridge. But my basement had old fashion grids so mouse/rat can easy get in and out so I had to deal with it urgently. Brandon came at a short notice and gave me a quote and said he can come and start the work in 2 days. The other companies I got the quote could only come after 5 days, some of them after 1 week. He also pointed out that my attic insulation is old and thin. And since he has to clean the attic (there were some mouse activities there too) he suggested it's not a lot of extra cost to put the whole new insulation. (I have been feeling cold in the house due to the old insulation so was happy to replace with a new one taking this opportunity). The crew (2-3 people) came for 2 days and fixed all the holes with the mesh in the basement, crawlspace and the attic. Cleaned the droppings, vacuumed the whole place, sanitized and set the traps. They even cleaned the duct in the house. It was a lot of money but with the amount of work they did, I was very happy. I bought the house 1.5 years ago and I wanted these things done anyway (duct cleaning, new insulation) so the mouse control was a good reason to tackle all of them. I would recommend Brandon and his team hightly.

He even came back to inspect another area, and give us various options. The crew did an incredible job on day 1: sealing the house while vacuuming out the old insulation and then sealing and sanitizing every nook and cranny. On day 2, they installed the new insulation. They again sealed areas to prevent debris from entering the house. The crew were suited up with protective gear and were very skilled at their jobs. I would highly recommend Rywen Insulation.

There has been this persistent smell of rodent urine in one of our closets for literally decades, no matter what we have done. Not any more! I could not recommend Rywen Insulation more highly for rodent control work. We've had rodent control people here before, but never at the level that Rywen takes things to. They put in place genuine long-term preventative measures to keep rats and mice out, not just patching holes. And that has made all the difference. No more smell in our under-the-stairs closet! And, I'm not sure if it is always a part of their service, but they offered us a one-year warranty. Rats and mice did return --- probably due to a contractor leaving our crawlspace door open overnight with the lights on, several times (oops). But Rywen took care of the problem immediately, no questions asked and no additional money requested, for the entire year of the warranty. They aren't cheap. But they are soooo worth it.
