Extensions- 8 Mar 2025
Charles and his team did a brilliant job on my double garage extension. Start to finish Charles and his team were really polite and clean workers. Charles was always in contact with me and giving me updates daily and always kept me in the loop at every stage. Project was completed to a really high standard, a very reasonable price and in good time! It wasn’t the easiest build due to a water leak from Thames water nearby causing a mud pool but it was still completed in a great time frame! I can highly recommend them for any works!

Kitchen Fitting- 17 Jan 2019
Simon was polite, efficient and very tidy. He listened to what I wanted (which was a little unusual), asked questions at each stage to make sure he was doing exactly what I wanted, advised when he thought an idea wouldn’t work and gave his own suggestions, communicated well with all the other tradesmen involved, got them all to do their bit in a timely fashion and worked very hard. I am getting him back to do another job imminently!

Kieran removed my old front door and rebuild the loose bricks to the front porch. Then fitted a new door and sealed the door. This was a job I started but could not finish so even being a Sunday kieran still attended and was one of the most polite and friendly builders I have worked with. The overall quality of the work was excellent and way better than I expected.

Extensions- 18 Feb 2016
I strongly recommend Richard (Ren Construction). The work was performed according to the agreed budget and scheduled time. Richard weekly informed me regarding each stage of the building, and its progression. Richard took control and plan a solution for any general issues related to the project, and also promptly responded after the completion of the work. On a personal level Richard is very easy to approach and to discuss the project with, and these are important qualities when you are dealing with quite a stressful time caused by the disruption of your day life; we kept living in the house during the building.

Based on my experience I have no hesitation recommending BCB Building Services who came recommended to me prior to this work by word of mouth. I needed to carry out modest renovation and remediation works on a newly purchased period property requiring many trades; general builder, scaffolder, plumber, plasterer, roofer, landscaper and damp specialist, etc. Brad and BCB team promptly provided a quote and, essential for me, agreed to source and project manage the diverse trades required to complete the work. They are busy but worth the patience and short wait necessary to get the work done by them. The workforce were professional, tidy, courteous and organised minimising disruption during the works and leaving the house clean and undamaged in their wake. The works were delivered per schedule and to a high standard and whilst not the cheapest, the pricing is fair and I believe the outcome represents tremendous value. Brad and the team remained pro-active beyond works completion and engaged actively in addressing the small amount of trivial snagging. They are now my go to for building works.

Conversions - General- 25 Apr 2023
This was work to a commercial unit. Jason and his team were absolutely excellent. Sensible pricing and started and completed the work as he'd promised. Removed all rubbish and left it clear and tidy. He organised an electrician and plumber and found a sensible solution for a damp problem that was uncovered during the works. Highly recommended...and nice people to deal with too.

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

An extension builder in Guildford 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 Guildford 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 Guildford?

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

Do you offer a guarantee for your work? Most Guildford 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.
