Great lads & did a great job
Great lads & did a great job, although the job was not estimated correctly (no change in price) just more complex than estimated. A few minor damages caused through the difficulty of the job, but nothing that can’t be easily fixed. In all a reasonable cost, a good job completed & a cosy home now.

GRS Cavity Wall Insulation
The initial contact and visit by GRS surveyor for cavity wall insulation was courteous, informative and friendly. Ditto for the 2 man installation team who worked away without any issues. On the basis of my experience, I would be pleased to recommend them to anyone.

Cavity Wall Insulation - GRS Insulation Ltd
GRS Insulation Ltd installed cavity wall insulation to my home for free. There was some issues with the installation, but the people from GRS Insulation Ltd worked hard to overcome the issues and installed the cavity wall insulation in a timely manner.

Installation team were efficient
Installation team were efficient, knowledgeable and timely.
Any issues were raised prior to work being done.
Clean up afterwards could have been better

Friendly team who extracted and refilled
Friendly team who came to extract original rock wall insulation and refill walls with bonded beads.
The job did take a little longer than normal as one area didn't fill correctly but the team came back a few days later to sort everything out.
Hopefully the installation will make a difference, but, as the weather has now turned a little warmer, we can't measure the effectiveness yet of the insulation.
We are happy with GRS.
