We recently had our floor insulated by Callengoed advies en isolatie and are extremely satisfied with the work performed, and especially with the fact that it was carried out. We had initially requested a quote from another company, but after inspecting the situation, they decided against doing the work: too difficult to execute, too narrow passages, and a crawl space that was too low. The men from Callengoed said: "It is difficult, but we can do it and we are going to do it." I have deep respect for the two courteous Polish workers who completed the job. Crawling under the floor all day, working those large rolls of material inside through a narrow hatch while lying down, and securing them under the floor. What a job. Hats off to those men. The administrative handling, including all the necessary documents for applying for the insulation subsidy, was also perfectly in order. In short: a company you can rely on.

Our experience: A year ago, we'd had cellulose roof insulation blown in. 16cm. The house was built in 1970 and had a 4cm layer of PIR. Now, we've had a winter and a summer. We have a different house, which isn't as warm anymore and doesn't cool down as much at night! We haven't installed a radiator in the attic yet; it doesn't seem necessary for the bedroom! What a relief. Barend neatly taped off the stairs and worked efficiently. Excellent job; I finished blowing in the insulation by 1:30 PM (I had installed the sheeting and battens myself).

Thank you for the excellent service and expert advice. They actively collaborated with us, including bringing in other experts and providing us with tips regarding subsidies. Very helpful! I highly recommend this company.

My roof was completely insulated in one day. They arrived at 8:00 AM and didn't leave until 7:00 PM. I practically had to force them to have coffee. Really neat and good work. They even cleaned everything. I had a good feeling from the first meeting, and they really delivered. They also helped me with the subsidies I was applying for. Hats off, you don't see that very often anymore.

Keurig antwoord , maar niet volledig. Ik zou graag in het aanbod verschillende materialen willen vergelijken. Ik vermoed dat ik nu in het aanbod de goedkoopste optie zie staan.

er is alleen te vermelden dat ze keurig op tijd waren en erg aardig waren , alleen helaas er stond water in de kruipruimte dus het feest ging niet door. Waar wij erg van baalden we hadden er naar uitgekeken , de vraag is wat nu , wij willen graag dat het werk toch gedaan word en wachten op een bericht van Gallengoed Hans Grijzenhout
