We have listed our common questions below but if you still have some questions?

Please do not hesitate to contact us

We will discuss and agree a start date with you. It usually takes around 2 - 3 weeks to identify and source matching bricks and complete all the legal paperwork. So depending on the status of current projects, we could start in 4 - 6 weeks.

The price we quote is guaranteed, NO HIDDEN EXTRAS. When we quote for your building project we will provide a detailed specification, broken down by room showing exactly what work is to be undertaken. There are no nasty surprises, we include everything. VAT is included as are any charges for waste disposal, scaffolding etc.

We require a 5% deposit to secure a start date, this is non - refundable but it gives you a 14 day cooling of period from the date of you signing your contract.

As a rule we only undertake a maximum of two projects at any one time. This enables us to agree a start and finish date with you. This also enables us to ensure we have tradesmen / builders on site everyday.

We will have tradesmen / builders on site every working day (Mon-Fri) from 0730 till 1630. (Weather permitting)

There is inevitably some unavoidable disruption involved. However unlike some builders, we believe in leaving the site safe and tidy at the end of each day, and that includes sweeping up, hosing down driveways etc. Helping to keep the disruption to you, your family and any neighbours that may be affected, to a minimum.

Don't just take our word for it - See what our customers think of our work

Adrian and his team have just completed a single storey extension on our house. We're extremely happy with the finished product and would have absolutely no hesitation in recommending him to anybody thinking of undertaking such a project in the future. The standard of work/finish and attention to detail is extremely high. Particularly pleasing and impressive was the way everything was cleared up at the end of each day. Had it not been for the portaloo on the driveway, you would never have known that we were having work done. Adrian has been extremely professional, honest and transparent with us, right from our first meeting with him, to discuss a quote on the proposed works, and has also offered invaluable help and advice throughout. He warned us that he'd probably be the most expensive quote, but told us you get what you pay for. Having previously had a less than satisfactory experience on a previous project, where we opted for a cheaper quote, I have
to say that he backed up that statement. He is always contactable and his communication cannot be faulted, always keeping you in touch and informed of progress and of any potential problems. Any problems that do arise are always clearly explained and always followed by a proposed solution, giving you great confidence and reassurance that you're in safe hands. In summary, definitely 5 stars, in the absence of a higher rating!
