The whole process from quotation, survey and fitting was brilliant. Just a really nice company to deal with; the quality of all the items we have had fitted are excellent. A big shout out to the fitters, Josh, Charlie and Ryan - what a dream team - they just couldn't have been more helpful and polite and left our house clean and tidy; they really knew how to do their job properly. 100% confidence in this company." > — Customer in Hampshire (5.0, via Which? Trusted Traders) > "We found KJM via Google whilst searching for 4 replacement windows with integral blinds. We visited their showroom and viewed some samples at the same time they give us a quote for the work. We set a date, for a visit, for them to measure up (check my measurements). Thankfully the original figure didn't change for the worse and we booked in the job. On the fitting day the fitters turned up early and had the job completed by around 3.30pm. I must admit from start to finish their service was excellent. I felt that they knew what they were doing and didn't hide anything from me. The fitters workmanship was super. They were friendly, helpful and and discussed the work as it progressed. My house is very old and getting the windows square didn't seem to cause an issue. All in all my wife and I are very pleased with the result and we have had lots of admiring comments from my neighbours. Would I recommend KJM to any prospective customer - yes I would in a flash." > — Customer in Wiltshire (5.0, via Which? Trusted Traders) > "To spread the load, KJM have installed windows twice and we have just booked the last phase. They have been very professional each time, from the initial measuring up, then the survey and finally the fitting. I cannot recommend them highly enough. The quality of the finished product has been very impressive, a real upgrade for us." > — Customer in Wiltshire (5.0, via Which?
