Conservatories- 14 Dec 2022
Kyle has carried out the removal and replacement of our lean-to conservatory. His advice at the initial visit and throughout the work was very helpful and he was prompt in submitting his quotation. Once the order was placed he informed us of the starting date and arrived with all the materials required which ensured that the work progressed quickly and was completed within the given timescale. Kyle was very competent, polite and friendly and cleaned up thoroughly after job was completed. We are very satisfied with the work carried out and from our experience would be more than happy to recommend K. Ransley Installations.

What to ask a Southsea extension builder before hiring?

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

An extension builder in Southsea 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 Southsea 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 Southsea?

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 Southsea 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 Southsea 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.
