After 1934 houses where built with empty cavity walls, these cavities range traditionally from 50mm to 75mm wide. The vast majority of this house type have had insulation installed in the cavity over the last 40 years.

Quick response to my missed call and came out the same day. We got in contact with Certainfil to ask about having our wall cavities filled. We didn’t need them done in the end because they had already been filled, but I was happily surprised at how quickly the query was sorted.

I enquired about getting cavity wall insulation through their contact page. I received a call on 12th Feb 21, I think he said his name was John. He told me that he had another appointment in glengormley on 15th Feb and that he would call around to see me after it, I write this review on Sunday 28th Feb, I'm still waiting! Totally unprofessional and unacceptable.

1st class and efficient service from start to finish for loft insulation. Ian called the same day I contacted him to check the loft. Fairly soon after this I got a call with the start date. The 2 boys who fitted the insulation where prompt, polite and helpful. Next day the vents were fitted on the roof. Again the fitter was prompt and polite even though I didnt hear him knocking the door. My apologies lol. Can't recommend this Company highly enough.

I couldn't recommend this service enough. The lads who installed my cavity wall insulation had to climb up into my loft to inject it. They were very courteous and tidy given the circumstances and did an A* service. It's like a different house now. Many thanks for a great job!

First class job, clean, tidy, and covid friendly. From initial response of query to the job complete was only a couple of weeks, even the neighbours got theirs done on same day. very informative, explained the process and the benefits. Different house now, should have got it done years ago and saved a mint in heating cost.

1st class treatment from start to finish. I was waiting on "another" firm (who said they were the best) getting me sorted and after being delayed for over 2 months and feeling I was doing too much chasing, I made the inquiry to Certainfil online. Got a response the next day, with an estimate and called 2 days later to survey and complete the job. Noticed the difference right away in the house. Excellent service all round. 5 stars easy.

From a hoody, jeans and blanket in the evening to wondering around in just the underwear. The difference a few hours with Certainfil makes to your life. If you have an unfilled Cavity, get Certainfil to fill it. Amazing service from start to finish. Clean, tidy, professional and friendly. My only problem is I wish I had done it sooner. Thanks Certainfil, you have saved me £££££ on heating
