Latest review:
Cristian and his team completely transformed our semi-detached home during this extensive renovation. His expertise was invaluable; he was incredibly helpful, advised us on the best layout and color options, and crucially highlighted structural risks regarding what needed changing versus what we could safely keep.His structural work was extensive, replacing weak wooden beams with strong steel beams to support the first floor, wall structures, and the chimney breast/flue removals that safely maximized our bedroom space.On the ground floor, he masterfully partitioned the living room into two bedrooms, extended the open-plan kitchen, added a modern bathroom with a new tub, rebuilt unsafe stairs, and converted under-stairs space into smart storage. Upstairs, he beautifully renovated a bathroom and converted bedrooms into a new kitchen, utility room, and spacious bedrooms. He also completely rewired the house, updated all radiator piping. Absolute professional

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.

Extensions- 6 Aug 2022
Majid has been great in producing drawings for our rear extension. He's also helped explain the whole build process to us from design, building inspection, and building. We received our drawings in under 10 days from the initial consultation and site visit. Majid was accomodating and was able to visit the site on weekends for the initial consultation. Always a pleasure to deal with and has been easy to reach over the phone or email. Would highly recommend Maji and MYD Studio London to anyone looking for an architect.

Extensions- 14 Mar 2022
Being our first extension project and not knowing any builders we were very anxious about selecting the right people, M & N builders were clearly the best of the bunch! What impressed us was their enthusiasm for the work and the understanding of what we wanted. They are a very professional team who kept us well informed and are also very efficient and like to keep a tidy working environment! We absolutely love what they have done for us and would highly recommend M & N to anyone and will definitely use them again in the future. Thank you M & N for your professional service.

What to ask a Horley extension builder before hiring?

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

An extension builder in Horley 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 Horley 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 Horley?

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 Horley 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 Horley 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.
