"We hired Tim and his team at ASH to undertake the project of converting our loft into a fourth bedroom . From the start Tim was clear and confident in the timescale and phases of the job and discussed with us our requirements and needs to best plan the use of space , they went above and beyond every day leaving things clean and tidy. The boys were always polite and professional and the completed task exceeded our expectations in terms of the space and light created and quality of finish. We would definitely recommend Ash to anyone for renovation/ improvement works for a high quality finish ."

"We hired Tim to sort out a crack at the apex of the rear of our property. It involved removing render, installing new blockwork and re-rendering the area. They also fixed an area of tyrolean finish that had come loose (and fallen off in parts), which they returned to original finish, painted the back of the property and replaced the roof tiles on a lean to. Having used ASH for a kitchen extension, we had complete faith in Tim and his team to carry out the work. The team are personable and courteous and always clean up at the end of every day. We'll be using ASH again for any future projects."

Before you hire a builder

Never pay a large deposit up front — agree a staged payment schedule tied to completed milestones, and hold a small retention until snagging is done.
Get it in writing: an itemised quote with scope, materials, start and finish dates, and how any changes (variations) will be priced.
Be wary of a cash-only price or pressure to start tomorrow — both are red flags for an unaccountable job.
Ask to see a portfolio of completed work like yours, plus recent references you can contact.
Check the credentials and registrations that matter for this work — and that they are current.
