Latest review:
Grant fitted our kitchen in December, to an extremely high standard. All filler panels scribed to the walls / floor even ones not on show. Everything perfectly level and fitted how it should, as it would be in a top end kitchen - this made us very happy as he made our dream kitchen come to life. We changed a coupling things halfway though. He had no issues adjusting to our changes, also advising of better options using his skill and knowledge. I cannot fault Grant in his workmanship, professionalism and reliability so much so that I have recommended him to several friends that have now had work completed by him and are more than happy.

Philip Baker Building, Carpentry and Property Services
No reviews yet
Extension Builder in Alton
Your house is your biggest investment you have and it an honour that you choose me to work on your investment. Hi, I'm Phil Baker and I've been in the building trade all my working life, 40 plus years. We try carry out only 1 job at a time, being there every day, every week, from start to finish. It's this "dedication " to just your job that stands us out from the other. To complement that dedication is our main tools in our arsenal !! Namely hoovers, dust extractors and dust sheets, the key thing to remember here is that after all, it's still your house and home and not a building site. After we have gone home it's still the place you have to eat and sleep, so it needs to be respected so. It needs to be as clean and tidy as possible !, so you can still function as a family safely. Many jobs we have been appointed over the years have come from prospective clients noticing how tidy the outside looks ! Tidy, neatly stacked skips, materials maintained neatly and covered over. After all, these are the materials you are paying for so need to be protected properly outside until used. A happy and good site gives you the best job results. Philip Baker.

Mr Timmins worked on transforming a dilapidated garage into a Grandad Annex for my father and his partner . The work was of an incredibly high standard in my opinion. Mr Timmins arrived early and left late. I wish I could send photos of the before and after it was amazing to see. I am in the process of contacting Mr Timmins again as I have some more building work for him and I do recommend him on a regular basis .
