Hydrostop Limited
Rating: 5 out of 5
Extension Builder in Northwich
HydroStop Limited are flat roofing and damp remediation specialists based in Wirral, covering the North West and beyond. We are a dedicated specialist trade — not a general builder — which means every job we take on is within our core expertise. Flat Roofing — Firestone EPDM Rubber Systems We have been installing Firestone RubberGard EPDM rubber membrane roofing since 1998 — over 25 years of hands-on experience with this system. EPDM is the premium choice for UK flat roofs: a single-ply rubber membrane carrying a 20+ year manufacturer-backed warranty that far outperforms felt and GRP on longevity and reliability. We install on domestic extensions, garage roofs, and outbuildings, to the correct specification every time. Damp Proofing & Remediation We diagnose and treat all forms of damp in domestic properties — rising damp, penetrating damp, and condensation-related issues. Every survey is carried out by one of our own employed surveyors — all of whom hold Level 2 Certification with the Federation of Damp (FOD). We identify the source, not just the symptom. Treatment includes specialist tanking, replastering with salt-resistant renovating plaster, and chemical DPC injection where required. We leave walls ready to redecorate. We are Verified by MyBuilder, registered at Companies House, and offer a warranty on all works. Fully insured, professional, and straight-talking.

Roofing (Flat)- 25 Aug 2026
Michael and Peter did a great job replacing our flat roof. The options were explained really clearly from the outset, including the pros and cons of a warm vs. cold roof. They gave us their recommendation on the best option but left the final decision entirely to us. They went above and beyond throughout and made sure everything was completed to a really high standard. The work was fairly priced, and they also managed to fit us in at short notice, which we really appreciated. We’re really pleased with the finished roof and would happily recommend them.

What to ask a Northwich extension builder before hiring?

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

An extension builder in Northwich 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 Northwich 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 Northwich?

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 Northwich 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 Northwich 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.
