Michael of Cytrek done a great job of restoring some of my rotten external window cills by removing the rotten wood and replacing it with new wood, plus filling, making them look virtually like new after he finished decorating them. He also done some Guttering and Roof repairs for me.

Richard is capable of installing windows but we’ve had a bad general experience with him starting with leaving the work unfinished initially and is now ignoring us to avoid having to rectify the issues he’s left us with. We now have a door which scrapes and sticks to the frame whenever it Is opened or shut. I wouldn’t recommend using Premier Home Improvements.

Gary Hagger

House Extension in Northamptonshire

We are a small two man team including me (Gary) a carpenter by trade with 35 years experience and Jay my right hand man who is by trade a plumber with 25 years in the trade. We have a team of other trades we can call upon whenever necessary including electricians, plasterers, painters, tilers etc and can do any job that may come along. Although always being self-employed, I have been working for the same guy for the last seven years. I was originally asked to fit three kitchens on some posh flats in St Albans. This expanded to all the kitchens in the development and then on to all the 2nd fix carpentry, doors, skirting, architraves etc. In short I ended up staying seven years which only ended recently. I met Jay four years ago when he came to work on one of the jobs I was on. We liked each other immediately. We worked together for three years for the same guy (mentioned earlier) and then, a year ago decided to branch out on our own. We’d both decided that work had got a bit staid and repetitive and thought that we needed a new challenge to get the blood pumping again. I live in Leighton Buzzard and Jay in Milton Keynes so we tend to concentrate our efforts in finding work to a 25 mile radius of both these places although for the right job we can be flexible. We pride ourselves in our high standard of workmanship and professionalism and like to think that we offer real value for money.

Reviewed by Linda on 18/12/2012

Gary did a very good job of building a wooden structure for my pergola. His craftsmanship was very good and he was sensitive to the work that had already been done in the garden. It was, however a few inches shorter than requested. The brief was to build a 'sheltered area' but he did not return as promised to refit the canopy. He had to attend a funeral, so since this was the possible reason I would still recommend him.

At no time were you told not to tile that area, that is absurd, why would we want an area not tiled. On the quote it was stated that you would remove old tiles and make good walls, having spoken to 4 companies since they all stated the same, this would mean plastering the same, we paid extra for this. Something to be considered when writing your quotes. The receipts for materials, second amount, never materialised. You were paid in full regardless.

George responded quickly to my request, gave a very reasonable quote, did a really quite tricky and complicated job above a conservatory, to fix cracks in the pebbledash of an external wall, and seal all around the windows. A fortnight later he re-plastered internally. George gives the impression of being somewhat chaotic! But he is extremely experienced, knows what he is doing, and actually did a very good job. The timings and quote agreed to were respected, he was polite and cordial, and communicated well
