Bricklaying- 26 Nov 2021
Nice chap. Sadly, texted us on the morning we were due to get materials (three days before starting) that he’d taken on another job instead. We were disappointed to not have been made aware sooner, and naturally not to have had the job done, but, trust it was unavoidable.

Bricklaying- 23 Aug 2023
Thank you Scott and his team for helping us to remove the french door and replace it with a wall and a window which were left uncompleted by the pervious builder. Within two days they finished the job without leaving a mess. They are very efficient and effective. The price is affordable. Scott did not ask us to pay any advance payments for the materials or project. We could pay after the job was done. That gave me more trust in hiring them again in the future.

Tiling- 24 Nov 2025
Honestly would never recommend this company to anyone. Everything started well for the first day was onsite all was good. Day 2 didn’t turn up to the job and no reply until dinner time when I get a call “sorry I slept in” they did end up coming to do some of the job only because their tools was left at my house. They had to come back due to not enough tiles which is not their fault I understand that. Told me they will there possibly on Thursday- no show then told me I’ll be there at “ some point” on the Friday never turned up. I spoke to him on the weekend and asked when are you coming to finish off the job he said 100% Monday - happy days going to get it sorted. Monday comes message on this app sorry I won’t be there this morning had my phone and cards all stolen will be there this afternoon. Yet again still no show! I have been without a bathroom for 16 days with a 6 month pregnant partner and have to get someone else to finish the job! And paid £700 for all this stress

Bricklaying- 13 Oct 2018
Build wall at the side of the house on which a new wrought iron gate was to be hung and replace cracked and worn bricks along the top edge of the front garden retaining wall, with brand new blue engineering bricks. Daniel arrived to complete the posted job at the exact time we had previously agreed. He coordinated and worked in tandem with another (independent) tradesman I had appointed to remove the wrought iron railings from the front of the house, have them galvanized and powder coated and then replace them, when the new bricks had been installed. Daniel showed an ability to get with other tradesmen whom he had never met previously and still do an excellent job. I am really pleased with the end result and have no hesitation in recommending Daniel for other jobs, where brick laying is required. My front garden looks so much better now that all the work is finished and I cant thank Daniel enough for a job well done.

What to ask a Runcorn extension builder before hiring?

Before hiring an extension builder in Runcorn or extension building company in Runcorn, ask a few key questions to make sure you’re choosing the right professional for your home extension project.

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

An extension builder in Runcorn 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 Runcorn 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 Runcorn?

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 Runcorn 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 Runcorn 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.
