About
Based in Carshalton, Surrey and operating throughout South London, Surrey and the surrounding areas. We are a well established, small building company with over 25 years experience. Many of the professionals that work with us have done so for 25 years and all work to the highest standards. We understand that having building work carried out on your property can be daunting, so our aim it to run each job as smoothly and professionally as possible, on time and on budget with as little disruption as possible. I only undertake one large contract at a time so from start to finish your work has my undivided attention.

Highlights
"I've used Jim for renovation work. He is a good worker, reliable - the sort of person you can leave your keys with whilst you go on holiday"
"Jim has carried out work on my kitchen and bathroom and I've never has any issues. Happy to recommend."
"He has been our builder for over 20 years and he is does all kinds of building and decorating work for us. I don't need anyone else and I definitely would never use anybody else. Am always incredibly happy. He is so trustworthy and he fits his schedule around me. Always on budget sometimes over time because I think of new things he can do to. Never any problems. If there are which is very rare, he is always back really quickly to fix it free of charge."

He has been our builder for over 20 years and he is does all kinds of building and decorating work for us. I don't need anyone else and I definitely would never use anybody else. Am always incredibly happy. He is so trustworthy and he fits his schedule around me. Always on budget sometimes over time because I think of new things he can do to. Never any problems.

Highly recommended. Jim is extremely professional with a particularly good eye for detail. His work is high quality and neat and he leaves everything clean afterwards, He is very pleasant to deal with and easy to contact when off site. He's clearly very experienced and has the knack of being able to explain things clearly. He's also good at offering ideas and advice. Very trustworthy and I'd certainly use him again.
I would and have highly recommended J Cullen Building. Our kitchen was completed to a very high standard, Mr Cullen and his team worked hard, communicated well throughout the process and achieved everything we hoped for.

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.
