Extension Builder in Northwood
I have spent 40 years in the construction industry, starting straight from school where I completed a five-year apprenticeship in the glass and glazing industry. Over the years, I progressed through all areas of the window and fenestration sector, gaining extensive hands-on experience in all types of glazing, window systems, fire doors, conservatories, and associated installation works. As my career developed, I broadened my expertise further by moving into carpentry and developing practical skills in a range of additional trades, including brickwork, tiling, kitchen fitting, and general building works, to name a few. This diverse background allows me to offer a well-rounded understanding of both specialist and general construction projects. We operate throughout Bedfordshire, Hertfordshire, Northamptonshire, and Oxfordshire, including all surrounding areas.

Windows & Doors (uPVC & Metal)- 26 Jun 2026
What can I say about Tony? Appears lovely to your face but appear he tells porkies. I'll summarise quickly - he came round, quote sounded good but wasn't quite right (colour was wrong for example) - if you asked for a tweak it took a while to hear back. He also said he'd remove the lounge window for £0 cost for our sofa delivery. It all dragged on a while. I chased it up and our sofa was actuallty being delivered. His wife said it was c. £500 for the window removal. He then did visit again (we found out we could do the sofa without removing the window so thought we would give him a chance) - he said his wife is a bit angry, hence the high cost for temp. removal. I asked for one last quote and wanted to go ahead..... nothing... I chased... &chased... he then replied saying he's closing down the business. Well look, here we are, 6 months later & he appears to still be trading. I feel a mug. I wished him all the best, thinking his biz was going under. Whole weird process went on 8 months.

Extensions- 9 Jan 2019
Altun Property stepped into the project very anxiously and positive. The management were very helpful and assist us with the neighbours requirements, as our building is adjacent to a primary school. The project went thoroughly and took some time because it was a big project. Altun Property were very energetic and supportive throughout the work, they didn't object any amendment the project required and extra work needed. We have received several compliments from visitors to our office for the level of work conducted and the quality provided. Commissioning the work to Altun Property helped us heavily as a charity because we were able to save on the overall cost of the work. I would like to express our appreciation for the work conducted and look forward for further work together.

What to ask a Northwood extension builder before hiring?

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

An extension builder in Northwood 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 Northwood 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 Northwood?

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 Northwood 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 Northwood 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.
