I had my loft fitted a month ago and the guys were brilliant from start to finish. I am delighted with my loft and the space I now have.

The team were lovely polite men turned up when they said took photos of everything they had done emptying loft out disposing of unwanted items and putting items back in loft when finished.

Brilliant company
Don’t bother looking at other loft installations and just book Karlsson!
I will only use reliable, professionals and that’s what I got, from start to finish, communication, staff presentation, time, cleaning, and experts who delivered excellent value for money, we had a couple of quotes and Karlsson was not only spot on, but they had brilliant reviews and now I know why.
We had 300mm loft insulation, Air vents, LED light, electrics, timber frame 16sqm boarded out and a loft ladder with draft proofing installed.
I would highly recommend them to anybody and thanks again.
