Groundwork & Foundations- 13 Mar 2025
The best contractor I’ve ever worked with—honest, reliable, and reasonable with pricing. He successfully completed the drainage job, installed 10 manholes and a hydro breaker, laid the road, and is now managing the site with 10 workers operating.

Carpentry- 25 Mar 2026
4 doors fitted, quote received initially for 3 doors, but changed to 4. Receipts for materials not provided, ended up paying a lot more for extra small jobs such as refitting a very small bit of beading. Also told door thresholds not included in quote even though I asked for this when he came round to quote. Part of kitchen door frame removed to help with door installation but not refitted well and a lot of chipping which was not rectified. Lots of nails/allen keys found around the house rather than piled in one area which is dangerous given there are children in the house. Lack of transparency with quote, quality of job and what was paid meant overall was not pleased with work.

Extensions- 20 Feb 2021
So disappointed with this builder who calls himself Jack , I really believed and trusted in him as he seemed so genuine yet he walked off the job half way through the build .He finished for the Xmas break and hasn’t returned , he has been overpaid for where the job is at , all extra additions we came across paid in full .He commented how hard I worked as an NHS Nurse yet he and his 2 workers never ever put a full day in finishing most days at 2 pm .I will be pursuing him for failure to complete the works and I have submitted a claim to the courts to retrieve some of the monies , I have also contacted Trading standards . I would not recommend this builder .

What to ask a Altrincham extension builder before hiring?

Before hiring an extension builder in Altrincham or extension building company in Altrincham, 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 Altrincham?

An extension builder in Altrincham 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 Altrincham 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 Altrincham?

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 Altrincham 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 Altrincham 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.
