Construction mastic in Toothill
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Different surfaces, different methods
Bathrooms, en suites and washrooms
On multi-unit schemes, consistency matters across hundreds of bathrooms. A single team keeps the standard consistent.
Window and door perimeters
Gaps around frames have to be within the sealant’s range. We check them during the first walk-round and flag any that need packing or adjusting.
Construction mastic in Toothill, done properly
External mastic depends on the weather in a way most internal trades don’t. Each sealant has a temperature range, and damp, frost or condensation on frames stops work. Internal sealing often fills those days. We work on brick and block movement joints, sanitary and kitchen joints and window and door perimeters, and the usual reasons a site gets in touch are sealant knocked or painted over by other trades and internal caulk splitting as the building dries out. Most enquiries from Toothill start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Around smaller places like Toothill, building work typically means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

Other services in Toothill
What happens if it’s left?
A cheaper sealant can look like an easy saving on a large package. The saving is small next to the cost of callbacks and defects and external joints are where it shows first. We price the specified product and will tell you plainly where an alternative would or wouldn’t work. Around Toothill, it’s better to renew all the failing joints at once. Send photos of each area and we’ll quote for the lot.
The price depends on the quantity of joints, what has to come out first and the access. Call for a fixed quote once you have the details.
What you get with us
- Failed material removed, not covered up
- Fully insured, including public liability cover
- RAL and finish matching where the product range allows
- 12-month guarantee on workmanship

Contractors’ notes for Toothill
The South East is one of the drier parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so the external programme keeps a little slack. Several hotels sit less than 2 miles from Toothill. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
School extensions, at buildings such as The Mountbatten School, normally run to the summer holidays, mastic included. Older buildings in the area around Toothill, such as South Stoneham House, 4.3 miles south-east of Toothill, need care when sealed: the product has to suit soft or historic materials.

Toothill: questions and answers
Can you work on a hospital site such as Romsey Hospital?
Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.
Is Toothill too small for you to travel to?
Not at all. Toothill is within our area. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
How soon can the area be used again?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.
Do you take on mastic snagging only?
Yes. We clear snags by redoing joints rather than patching them to suit the programme.
Is it fine to apply new sealant on top of old?
No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
Can fire-rated sealing at service penetrations be included?
Fire-rated sealing at service penetrations and linear gaps can be included where specified. Record requirements are confirmed at quote stage.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and we will price the work to it.
What sets the cost
Quotes vary with the job. It mainly depends on:
- The size and state of each joint
- Working within restricted access windows
- Location, for remote and island sites
- Specialist products, such as fire-rated or hygienic sealants
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.
Details that help us quote
The more we know, the firmer the quote. Helpful details to send:
- Specification clauses that apply
- Whether an asbestos survey exists
- Your programme or deadline
- The postcode of the building
A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or give us a call on 01277 525 020 or email a schedule or drawings to discuss it first.
Signs you need construction mastic in Toothill
Three-sided adhesion is a frequent fault on new work. Bonded to the base of the joint and both sides, sealant can’t stretch evenly, so depth is controlled with backing rod or bond-breaker tape.
Look out for the following:
- Frame gaps too wide for sealant alone
- Early adhesion failures on new external joints
- Failed sealant in an existing building being refurbished
- Snag items on joints that need redoing before handover
Building work at universities like University of Southampton, 3.8 miles to the south-east of Toothill, is often timed for the summer, mastic included.
What your quote should include
- Which product they’ll use, and why it suits the joint
- Their pre-qualification and accreditations
- How they’ll work around occupants
- Will failed sealant be removed rather than covered?
