What's actually included in a boiler service?
Combustion analysis, flue integrity check, gas tightness test, inspection of seals and pipework, a check of controls and thermostats, and a pressure and expansion vessel check. You get documentation on completion recording what was tested.
Is it worth repairing my old boiler or should I replace it?
It depends on the age, the fault and the cost of parts. As a rough guide, once a boiler passes 12–15 years and the repair runs to a meaningful share of a new unit's price, replacing usually makes more financial sense. We'll give you both figures for your Houston property and let you decide — we don't push replacements.
Is a service the same as a CP12?
No, and it's worth understanding the difference. A CP12 confirms gas appliances are safe to use, which is the legal requirement for landlords. A full service goes further, covering efficiency and wear items. Many landlords book both together in one visit.
Do you install new boilers in Houston?
Yes. We supply and fit A-rated combi and system boilers throughout Houston, including removing and disposing of the old unit, commissioning, balancing the system and registering the manufacturer warranty. Sizing advice is honest — we fit what your home needs, not the biggest unit we could sell.
How long does a service take?
Usually 45 minutes to an hour for a single boiler, assuming reasonable access and no faults found. A CP12 covering several appliances takes a bit longer.
My radiators are cold at the top — what's wrong?
That's usually trapped air, and bleeding the radiator often fixes it. If it keeps coming back, or radiators are cold at the bottom instead, that points to sludge or a balancing problem rather than air. Plenty of the village properties and family homes, a good share with older boilers in Houston have systems old enough for build-up to be the culprit.
Will servicing void or protect my warranty?
Protect it. Most manufacturers require documented annual servicing as a warranty condition — skip a year and a future claim can be refused even if the fault is unrelated. Keep the paperwork we give you.
Can you help with plumbing as well as boilers in Houston?
Yes — we're not boiler-only. We handle kitchen and bathroom plumbing, taps, showers, toilets, hot and cold pipework, leaks and drainage across Houston. It often means one visit sorts several jobs instead of booking separate trades.
When is the best time of year to book?
Late summer or early autumn. Everyone books in the first cold week of the year, so slots get tight exactly when you most want one. Servicing before the heating season starts also means any fault found is fixed before you depend on it.
What areas near Houston do you also cover?
We regularly work in Bridge of Weir, Bishopton and Johnstone as well as Houston itself. Our coverage runs across Greater Glasgow and into Renfrewshire, so if you're nearby but not listed on our site, it's worth a quick call to 0141 374 0545.
