Had my windows and doors supplied and fitted by Senator Windows very happy with the advice I was given regarding security of windows and doors and different designs of windows I could choose from. Good Experience.

Senator Windows replaced windows at my house and I am very happy with everything. The fitter was very neat and tidy and Senator Windows provided a fantastic service to me. Would recommend Senator Windows.
We are very pleased with the complete end to end job. The quality of your sales service, product and installation was excellent. The installation crew cleaned up each day, and taking into consideration the size of the job, my wife and I were very satisfied with the end result.
