Had a sky high quote from them a few months ago which we chose not to proceed with and now they call us literally every day. We have blocked the number. If we answer and say we are not interested the calls stop for a few weeks and then start up again

We wanted a quote for a sliding door for our back porch and the salesman quoted over 6k and then he dropped the price to 2 times! They try to pressure you and that if you dont sign today you wont find a better deal! Salesman ask what your job occupation is which has nothing to do with your quote and are fishing for how much money they can squeeze out of you. I keep getting calls even though i have told them multiple times i am not interested

What happened to GDPR?!!! Crystal windows from Romford ringing me - no idea how they got my number and I don't need new windows.

Aggressive sales pitch and massively overpriced before the so called discount if you buy before a certain date / time. Questionable reports on their quality. Would not recommend

Calls continually in breach of my TPS entry and refuses to stop calling. Hangs up when I mention TPS.

They ring and are screened out by our Call Guardian which blocks any caller who won't announce their name. Called us Sunday at 12 noon

Wouldn't touch them with a bargepole! Utter charlatans.

They sell very poor quality windows, after intense harassment, pretending they are high quality. The agent shows you high quality but they fit low quality. That's how they make their high profits

Hung up when asked to declare who they were by Call Guardian

Telesales for some very expensive windows.

I have had two houses done with Crystal windows, any problems they have re visited at no cost, windows were at market rates, it depends how you negotiate the right deal. I am afraid sales is sales in most industries

This company have bad reputaion in the Romford area for pushy sales and high price they do not take no for an answer . However if you have aphone that blocks calls put this number on block

CrystalWindows telepest 01708772410. Got a quote for windows, overpriced and worse quality than local supplier who offered German A-rated windows for less than half the price. Crystal Window hinges appear poor, does not offer any easy clean hinges. Crystal salesman tried to pressure to sign deal. Thank you but no way! We do compare both quality and price. Now we receive calls from Crystal Windows even if we opted out from marketing calls. 40% off voucher a complete joke. And did you know,according to their salesguy it does not matter do you order 5 or 1 window, the installation will cost the same for the team installation team to come. 1 crystal window installed about £ 1000, similar window online (no installation) around £ 100 / each. Still 7 windows installed quoted at £ 7600 with the 40% discount the voucher entitled to and an additional 10% discount providing that we sign up immediately. Funny guys. If you don't sign up they will email you that they have an even better offer! Really? just a little bit less ripped off? If you didn't know a window is held in place with 4 nails/screws so takes about 15 minutes to change including cleaning up the rubbish
