G2S have just finished fitting our new Windows. We had them done in 2 stages, as we were so impressed with the front we decided to get the back done. The whole process only took 2 days to complete the fitting. We found G2S very polite,professional and efficient. The Windows are a stunning addition to our home and were definitely value for money. We would recommend them very highly

Communication from G2S Group was great, we were kept fully informed on quotes, surveys, costs and fitting dates. The two staff members turned up at the time arranged and were both very polite. Our new back door was fitted in very quick time and the work area was kept clean both during and after the installation. We were shown operation of the door before they left, and they removed and disposed of the old door for us. Very pleased with the whole process. Highly recommended.

I bought my new rear garage door from this local company and I'm very pleased with the result. The initial survey was professionally done and the product was made and fitted on time with no mess left for me to clear up.
