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.

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.

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

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

What experience do you have with similar extensions in St Helens?

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 St Helens extension builder’s ability to deliver a result that meets your expectations.
