Extensions- 21 Jun 2017
COWBOYS! Absolute Nightmare! Marius left the job incomplete, after repeatedly demanding more money before completion! Not to be trusted! Workmanship wasn't as good as he would lead you to believe, I have pics & videos of: Cigarette butts in mortar. Bricklaying in the rain, not water-tight roof/felt work, drainage, unsafe electrical work which needs to be redone. Left my neighbour side of roof damaged + with a hole now for a month. Damaged door/table/gate. Of course, he denies any wrongdoing Please be very careful if you have to use this fraud. Get a FULLY detailed itemised quote! Draw up your own contract - do not use his. Do NOT ever pay CASH. Produce a schedule of works - pay him ONLY when the specific task is 100% complete - leaves lots of work unfinished but then lies claiming its complete at interim payments. Get a FIXED price for every aspect of work - do not have "TBC" or ambiguous costs - if he can charge more - he will. Do NOT use his electrician, cringeworthy attempt to "price up" a simple job and damaged roof. Buy ALL Materials yourself OR require receipts for anything he buys. Request ALL Invoices. Ensure he follows specs - offered me £250 off total job cost, if I used a inferior type of rooflight to the one required in spec. Ensure he doesn't keep rubbish on site, Hire a skip. Keep all communication on record, email, text, even voice record him as he is a pathological liar. Very dishonest, delusional and frankly embarrassing.

Bathroom Fitting- 9 Feb 2019
Extremely pleased with the job Remi did. At the quoting stage he was upfront about costs we might not have considered, but still ended up being very competitive on price. During the job, he communicated clearly when he came up against issues; his fitting was to a high standard; he was on time and worked as long as he needed to each day to finish the job. His after-care was also good, as he returned to fix a related issue that arose during the work without quibbling; he also came back to complete fitting an item whose delivery had been delayed. Overall, I'd definitely hire him again.

Akash made sure the job was complete exactly how he said it would be, he provided reliability during the installation of our kitchen and answered all questions very professionally. The builders were well aware of the conversations my mother and I had with Akash and so put our mind at ease. The installation itself was very quick (the tear down was very much completed in a few hours) and installed over the weekend. They were very hygiene aware and set up a cover between the kitchen and the rest of our house and didn’t disrupt our home living. They cleaned up before they were gone to very high standards without us even asking them too, all I’m sure is due to Akash’s excellent organisation skills.

Extensions- 2 Aug 2023
JLita construction were hired after a competitive quote was agreed to carry out work on my kitchen extension project last year. Prompt and dependable Jetmir’s team worked productive long hours with a clear understanding of my wants and requirements. Where it was possible to accommodate they did. Any remedial work was quickly picked up and completed in good time to the required specifications. After completion of work each day, the space was swept and tidied and the space made as usable as possible. I am extremely happy with the work carried out and the attention to detail applied by Jetmir and his team and would, (and have already) happily recommend JLita Construction for any building works. More than satisfied. Many thanks Jetmir and team. Scott

What to ask a Whetstone extension builder before hiring?

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

An extension builder in Whetstone 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 Whetstone 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 Whetstone?

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 Whetstone 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 Whetstone 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.
