What Harrow Homeowners Say About Our Plumbing Specialists
New mains water tap and external garden hose-bib in our Harrow 4-bed detached. New thermostatic mixing valve at the cylinder for safer hot water. Total £2840 over 1 days. Old galvanised pipework disposed of safely - WEEE-compliant. Boiler runs much quieter than the old one.
Hot water cylinder weeping at the base flange - plumber from BestBuilders responded within 3 hours. New stop tap fitted alongside a new isolation valve for future works. Cost £570 all-in. Followed up by phone the next day to check everything was still working.
Five months in and the underfloor heating zones are working in harmony. Plumber we found via BestBuilders in Harrow oversized the flow-and-return pipework so we could add radiators easily later. Total £4380. Genuinely no part of the install I would change.
