How FixMate works in Damp Specialist

Damp Specialist services in your area

Our plumbers in E8 operate 7 days a week, including evenings and bank holidays. For genuine plumbing emergencies — burst pipes, major leaks, no water supply — priority dispatch gets an engineer to you faster. You'll see the fixed price before confirming, and nothing changes on arrival.

Every FixMate plumber working in E8 is vetted before joining the network: ID verified, trade qualifications checked, and references confirmed. For gas-related plumbing work, Gas Safe registration is mandatory — engineers carry their Gas Safe ID card on every job and present it on arrival. You can verify any engineer's Gas Safe number at the official register.

Transparent pricing is the core FixMate model in Hackney: every price is shown upfront, confirmed in writing before work starts, and does not change unless you explicitly approve additional scope. The engineer cannot invoice for anything not agreed beforehand. This is enforced at the platform level, not just a policy promise.

FAQ

Frequently asked questions

Everything you need to know before booking.

Rising damp shows as a tide mark up to 1m above floor level with salt deposits. Penetrating damp appears at the point of water entry — usually a single wall, often after rain. Condensation forms on cold surfaces, especially windows and corners, with black mould patches in bathrooms and kitchens. A FixMate damp survey with a moisture meter confirms the cause in a single visit.
Most London properties built after 1875 have a physical DPC. Where it has failed or is missing, a chemical injection DPC is the modern equivalent — drilled at regular intervals along the affected wall and sealed with a water-repellent solution. We will advise at the survey.
Black mould (Stachybotrys chartarum) can aggravate asthma, trigger respiratory symptoms and cause skin irritation. It should be treated promptly, and the underlying moisture source fixed — not just the visible mould.
Mould-resistant paint typically prevents regrowth for 3–5 years if the moisture source is fixed. Without addressing the source (condensation, leak, rising damp) it will return within months.
Yes — where existing plaster has been contaminated by salts or mould, we remove it and re-plaster with a salt-resistant render. This is quoted separately after the survey.
Yes. Every FixMate damp specialist carries public liability insurance and is referenced before joining the network. ID is shown on arrival.
