Bricklaying- 25 Aug 2024
AVOID. Ernie incorrectly installed my drains under my house which has caused awful smells and sewage to leak under my house causing long term damage to my foundations Three professional drainage company’s have put a camera to see a Dropped pipe from new to old house. They have identified a connection that was never appropriate. Unfortunately, Ernie after being given many opportunities does not accept any responsibility. He is not an expert at all trades so be careful. I’ve asked him to help put right by exposing the floor which has Underfloor Heating. This has now cost me tens of £000s. My fault for not using a professional team at the beginning of my project.

We hired this builder for a 2-metre rear extension and a very large garage extension and we’re really happy with the result. The project needed a pile foundation which is a bit more complicated, but they handled everything very professionally. They listened to what we wanted and kept us informed at every stage, which really helped as we were living in the house while the work was being done. The team were friendly, easy to deal with and worked to a good standard. Overall a very good experience and we would happily recommend them.

Restoration & Refurbishment- 25 Feb 2020
Malcolm and his team did great work on my house. The job consisted of full house redecoration, building bespoke shelving and built in wardrobes, loft boarding and installing ladder, replacing fencing and general pruning in the garden. They were able to turn their hands to all manner of jobs. Malcolm had a full team onsite every day and they finished the work ahead of schedule. At all times Malcolm was very responsive and worked hard to ensure that any changes along the way were accommodated. I would happily recommend Spring Construction and would not hesitate to use them again in the future.

Extensions- 30 Sep 2025
Overall, I’m very pleased with the work Marin has carried out for us and I’m currently in the process of instructing him to do more work. Marin built a high spec cedar shed for us with electrics and plumbing, some brickwork and laid composite decking. Marin came across, honest and reliable, which in itself is rare. He was on site most mornings to make sure his tradesmen were on the right tracks. Like with a lot of these things there were some issues along the way and I was highly impressed by Marin’s ‘no quibble’ approach to rectify any problems. I myself have a high attention to detail and am quite indecisive (nightmare client) and Marin was happy to work with me with changes to the project without incurring extra costs.

Pawel and the team did a fantastic job. The bathroom looks superb and the whole team took time to finish the job to a very high standard. There was a narrow timeframe in which to do the work and this was met (despite more effort than first thought with respect to strengthening the floor). Pawel was easy to deal with and contacted me after the job to ensure everything ok. Highly recommended.

Bathroom Fitting- 16 Jun 2024
Harpreet not only finished this job, being kind, helpful and professional, ended up renovating some of the house hold things like changing gas hob, firting tiles etc, which I was thinking of doing later in year. He completed all the work in the time frame and amount charged was reasonable. He did great job in renovating the bathroom. He went out of way to help install loft stair case. He was always available to answer any queries. Would recommend

Landscaping- 4 Oct 2024
One word to define this 'company' COWBOY builders. Numerous issues one after another. Had to get 2nd/3rd opinion on their work to make sure I wasn't being fobbed off. Conducted loads of research which meant left being uneasy especially as a large chunk of payment was made after only 1 day of work when in fact payment was due end of completion. 1- Underestimating material costs 2- Slabs off the walkway coming loose within 2 months of being put down 3- Ignoring attempts of rectifying the flawed job 4- walkway was meant to be clear of grass and strictly shingles but grass/weed still appearing. 5- Forgot to state ground levels would be raised then creating a lie saying I had been told 6- denying and ignoring the obvious Wouldn't trust the reviews being left here and definitely wouldn't use or recommend them to anyone. Have decided to give up on trying to get them to fix their shoddy job and find someone else to fix their mess Correction - you was aware & agreed with mat delivery

Ali was brilliant at fitting my tap - it was more complicated than we thought and he stayed longer to make sure it was done, and even came back the next day to fix something that had gone wrong. Mohammad was brilliant, helping me with every enquiry and always answering really quickly, and patiently - super helpful. Overall, excellent - really happy - would definitely hire again.

An extension builder in Stratford 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?

What experience do you have with similar extensions in Stratford?

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