GRS Insulation LtdReviews 

The team ho came to the house where polite and professional

The professionalism of the installers

Good workers helpful for giving me information good job good

Communication within the company should be improved among employees. The left hand frequently did not know what the right hand was doing. Information gathering systems were not optimal. We received numerous emails and telephone calls about the same paperwork. There was a lot of unnecessary duplication. Most of all, we were given the wrong information which led to disappointment when the promised improvement could not be carried out.

In January 2025 we were seriously let down by an insulation company based in Wolverhampton. After nearly nine months of constant heartache we finally managed to get our money back. We looked around for a local company and were recommended to use GRS Insulation Limited and we have never looked back. They inspected the loft area and advised us on the work to be carried out. They also advised us to approach the local council for a possible grant which was approved. Since day one the company have always been upfront and most importantly honest. The guys who came out and did the actual insulation, installation of the two air vents and loft entrance and boarded area were excellent. Finally to the team in the administration office who were always at the end of the phone if we had any questions and even paid us a visit on a counter of occasions. Thank you one and all for being such a star team.

Friendly and helpful staff, arrived on time and seemed to work efficiently but left a lot of brick dust all over wall lights. House feels warmer already!

After a year of disappointment with the cavity insulation industry, I finally found a company that were interested in the customers needs, not thier own.
Installers were friendly, knowledgable & very helpful to have a good job completed.
Would certainly recommend against other companies I looked at & used.

From the initial assessment of the property to completing the required cavity wall and additional loft insulation, GRS staff were exemplary. Everything was explained and good communication between the office and myself was maintained throughout. Installation was completed in good time and the premises were left in a tidy state. The installation team worked hard and efficiently and were polite and communicative on site. I'm very happy with the work that has been done.

From noting my requirements on the Bark website GRS contacted me straight away and organised a visit within 24 hours. I received the quotation the same night. I accepted the quotation to go ahead with cavity wall insulation and removal and replacement of loft insulation. The price was very reasonable.
Jason and Ollie arrived as confirmed on the day. Both of them were very hardworking and polite. Even though there were a couple of unforeseen issues with the loft and the job took slightly longer than anticipated the communication from them was great and they kept me updated along the way.
Would definitely recommend.

Just a little messy.. That's all

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.

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.

From start to finish GRS acted in a very professional way. They offered advise and information regarding the service they were offering. Thier operatives were of a high standard and carried out the installation efficiently.

GRS Insulation were very efficient and kept me up to date with dates and installation information so I could inform the landlord and tenants.

This company were so easy to deal with from start to finish they installed wall cavity for us and made an excellent job definitely 5 star 🌟 rating .

Fair price. On time. Done well. Tidy job.

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.

The staff were amazing, helpful, efficient and totally went out of their way for us when were going through a very difficult time. The workmanship was spot on I would 100% recommend this company

Mega quick from quote to installation. Reasonable price. Professional and friendly both for quoting and installation !!
