Unfortunately I made the mistake of inviting CR Smith to my home to discuss a new front door, after speaking to their rep in B&Q. What started as an amicable conversation became quite nasty when the sales rep Stuart realised I wasn't going to buy a door that evening. Hard-sell lines such as 'are you the type of person who walks past a sale then comes back and buys the item at full price' were used, as was some ridiculous process of coming up with an apparently random price which, despite various "discounts" being applied, turned out to be about 800 (over 30%) more expensive than what I found the same door for elsewhere.

Despite what they make out, CR Smith do not produce their own 'Timberplus II' doors - they are a reseller/installer for Solidoor, and there are much cheaper and friendlier companies selling the same thing; check the Solidoor website for details.

There finishing touches. Have to leave a 1 star as it won't let me give them a 0. Cracked patio glass. Holes and dents in my walls. 4 times someone has been out sofar because doors would not lock. Windows not fitted properly so needed fixed. Windows and doors not sealed properly leaving holes and gaps round them all. Gray windows frames that where not painted properly so someone needed to come out with a PEN to touch them up. Dents holes and rips left in my flooring and they don't want to pay for all there damage to my property as Mark said it's not in his report.

Recently moved in to a new build home in the Cowdenbeath area and we have CR Smith windows fitted. They look great and we've had no issues at all with drafts or condensation. The safety locks are great for leaving windows open when kids are about and the easy adjustment to open them out fully so you can clean them inside and out yourself is brilliant! Would recommend

Well, I'd like to write a review, but after asking for a quotation (or even estimate) heard nothing more. I had actually visited their office in Dunfermline and handed over my window measurements and email address after discussing sash windows with 'Adam'. Several weeks went by and still nothing. When I visited my local B&Q there was a CR Smith rep at the entrance, promoting the company. I asked if he would look into it. He agreed and now several more weeks have gone by.nothing! (And yes, I've been checking my junk-mail folder). Weird.
