A very professional, yet personalised service, a great company to deal with overall. The surveyor was able to come up with an idea for the inward opening porch door I so wanted and the installers were quick, efficient and left the area clean and tidy after each installation. A great company and a local business too. Very pleased. Thank you GIS.
Friendly and professional advice combined with great value. We had previously used a national window chain for our back windows and found GIS better value for our front windows. We also appreciated a fixed quote they gave us for the time we needed. The fitters worked hard and to time (in the rain) and the after service has been great.
