Conservatories- 16 Feb 2021
We have used Skeffington Properties for the last two jobs on our house. The first was resealing of the conservatory and second was sorting our porch roof out to stop a continuous drip that started last week. Both jobs completed promptly after our requests and tidied after themselves. Thanks

Bricklaying- 20 Oct 2025
Excellent work. The old stone and brick barn required a good level of work to stabilize and repair prior to a new roof being fitted. Nick advised the best and practical way forward. The stone pointing and rebuilding was very good. Removing the existing roof timbers and stabilizing the end walls. Repairs to the brick work and the fitting of the new roof timbers ready for the new slate roof. Green jacket (Nick) were very reliable and commercially very fair. I did not want the cheapest quote, I wanted the most realistic and informed, Nick completed the remit completely. This project will require work to be carried out in different stages and Nick will be called in on several of the following works. Would recommend anyone to use Green Jacket.

Conversions - General- 22 Aug 2025
I hired Chris to install an RSJ, and I couldn’t be happier with the service. From start to finish, communication was excellent — he took the time to explain the issues uncovered during the work and talked me through the best solutions. His professionalism and problem-solving skills really stood out, especially when dealing with the poor building standards left behind by a previous builder. He also took care of building control and ensured everything was signed off properly, which gave me complete peace of mind. His team were polite, professional, and worked efficiently. The job was completed in a timely manner and with real attention to detail. I’d highly recommend Chris to anyone looking for reliable and skilled builders — a true professional you can trust.

Restoration & Refurbishment- 20 Jun 2026
I can’t rate Luke and his team highly enough - they were exceptional. They fitted the new kitchen, did the complicated electrics, carried out joinery, plastered, tiled and painted (as well as rectified a nasty area of damp) all to an extremely high standard. Each one of the tradesmen were polite, professional and a pleasure to have in our house. Luke provided a very detailed quote and fulfilled all his obligations to the letter. We are pensioners with health problems so it is essential that we can trust tradespeople: Profurb are reliable, clean and tidy, and highly skilled. What could have been an anxious renovation project was smooth and hassle-free. I’d recommend Luke, Jimbo and the other members of the team without hesitation. (Oh, and the kitchen-diner looks wonderful!)

Bathroom Fitting- 15 Jul 2023
Andy delivered what he’d promised and exceeded expectations. From first contact in April to completion today (15th July) he has been courteous, professional and has consulted us as necessary as the work has progressed. Problems that were not obvious when he attended site to work up his quotation were all addressed and without exceeding his original quotation. Andy and the tradesmen he uses for work he needs support with are thoroughly reliable. He turned up when he said he would and came back to finish off at a weekend, which was appreciated. We would highly recommend Parnaby Property Developments.

Carpentry- 15 Aug 2025
Could not recommend or rate Karl higher if I tried, after recently becoming a homeowner I had Karl come and give me prices for some jobs I wanted doing, initially the skirting boards, after talking to him and realising just how versatile he was he ended up doing most of the house. He’s completed a media wall, moved a stud wall, completed panelling in a dining area, fitted wardrobes and acoustic panels, laid flags in the fireplace and in an emergency he managed to fix a massive cracked pipe with a leak behind a wall and saved me a fortune. His prices are so fair, especially for the quality of the work, he treats the job as if he was working on his own home, nothing is rushed and his focus is on doing the job properly. Really nice fella and easy to talk to about the work that’s going on, already have him booked in to do more jobs, my house would be nowhere near where it’s at now without him

Extensions- 13 Nov 2022
Excellent from start to finish I can't praise Dave and his team highly enough. Great communication before and throughout the work. Comprehensive estimate to start with laying out every detail of the work. The work started on time and they worked every day till the job was complete. Dave was happy to add extra jobs as we went a long and always had great ideas to make the finished extension even better than we imagined. Dave made what could of been a very stressful experience as easy as it could be. The job was left very clean and tidy at the end of every day. I now recommend Dave to everyone. Dave is coming back next year to rebuild our garden wall and I'm sure we will be having more work done in the future. I have never known anyone who can do literally any building job to such a high standard.

Carl did a fantastic job installing skirting boards in my recently renovated house. He also installed two doors on the boiler cupboard and a raised children's seating area under my stairs. He was very helpful and worked hard while keeping the house very clean. I would recommend Carl and would use him again.

What qualifications and experience do you have as an extension builder in Holywell?

An extension builder in Holywell should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

Will my home extension meet all building regulations and planning requirements?

Your Holywell extension builder should ensure the project complies with Building Regulations and, where necessary, handle or assist with planning permissions. Ask how they manage building control inspections and what documentation you’ll receive once the project is complete.

What experience do you have with similar extensions in Holywell?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Holywell extension builder’s ability to deliver a result that meets your expectations.

How long will the extension take to complete?

Extension project timelines can vary depending on size, complexity, and weather. A typical single-storey extension might take around 8 - 12 weeks. Request a detailed schedule so you know what to expect and when key milestones will be reached.

Do you offer a guarantee for your work? Most Holywell extension builders offer a guarantee or warranty on their work, often between 1 and 10 years depending on the project and materials used. This gives you assurance that any issues will be resolved after completion.
