SEHBAC Windows & Doors Ltd

I had 2 doors installed at a cost of £4700 a few months ago and took out an interest free loan that was offered to me by the company. As I didn't have to settle the total for 12 months I thought it was a good deal. I had my concerns during the initial install where I could see daylight coming in through the bottom of one the doors. I pointed this out to the fitters and they adjusted the door but the following day I could feel cold air gushing in from the bottom of both doors. I used my thermal camera and could see that the bottom of both doors were compromised and not sealed. I raised this with the company and since then have had 4 visits adjusting various parts of the door. One of the locks was not engaging which they fixed by moving the frame and packing it with fillers. The threshold seals had to be turned around so they could make contact with the bottom of the doors because the threshold had been installed too low in relation to the door. I still have cold spots at the bottom of the door because of the low threshold and the only way to rectify this is to remove everything and start again. The initial install took 2 guys 6 hours. For that I was charged approx £2000 for the labour and got a terrible job which still isn't right. I have asked for compensation and the company have ignored my email and advised the loan company that I was happy and that they should release the money to them. This is really an appalling unethical way to run a company. I have notified the loan company and will see what their response is. I urge anyone to think twice before using this company.
