I have to admit, I am quite difficult to please when it comes to paying for work to be done to our house having seen my perfectionist father do many top DIY projects over the years; I have high expectations from trades people who do work for me. The key factors in my opinion were that the windows should fit well and be properly installed, to gain maximum heat saving benefit. To this end, the windows were measured by somebody with a background in surveying and then they were fitted by a fitter who was conscientious and took pride in his workmanship. The process of getting quotes from 2 other suppliers (Everest and Anglian) was not something I would like to do again in the next 2 decades. I had the usual sales patter, starting off at prices which would buy you a terraced house 'up North', then offering huge discounts - and then further discounts as they had a 'promotion in our area' and I even had to listen whilst one chap phoned his sales manager to see if there was any more discount that we would qualify for. I am so surprised that some replacement 'windows & doors' companies are still employing tactics that they used 40+ years ago, it's insulting to be honest. The initial visit from Derek at Omega was very brief by comparison to the other 2 companies and the quote followed shortly afterwards. There was no discounting or 'flannel', just the bottom line price. Simple. Derek kept us well informed on every step of the process. Regarding the installation, there was little or no damage to the window recesses, just a bit of 'touch up' painting to do. The fitter Alan was very industrious and methodical, checking with a spirit level etc. We had a range of windows fitted, including a bay window and 2 sets of French doors. The beautiful windows have transformed our house, in particular our utility room looks really smart now and I am extremely pleased with the profile which allows so much light into the rooms. The doors close with a reassuring clunk, like a good quality car. We would have no hesitation in recommending Omega Lifestyle, they have a quality product, it is fitted well and they are very competitively priced. We will use them again when we have an extension built.
