About our construction mastic in Brock Hill
Mastic is often where a new building first shows its quality to the client. A smeared bead round a window or a gap behind a worktop ends up on the snag list, and every return visit costs time. We seal so the snag list stays short, whatever the size of the scheme. Site teams most often ask us about frame gaps too wide for sealant alone and early adhesion failures on new external joints, across brick and block movement joints, window and door perimeters and sanitary and kitchen joints. Whoever orders the work in Brock Hill, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Around smaller places like Brock Hill, building work usually means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Do you need construction mastic in Brock Hill?
Shrinkage and settlement in the first months put new joints under strain. Materials lose construction moisture and shrink and internal caulk in a moving joint is usually the first to crack. Choosing the right product for each joint reduces that.
Typical triggers for a call:
- Bath and shower joints scraped during the final clean
- Caulk cracking where joints are moving more than expected
- Window and door perimeters that won’t pass inspection
- Mastic snags holding up handover
Extensions at sites like Mayflower Community Hospital (to the west of Brock Hill) normally sit beside working departments, and the mastic follows strict access rules.

Questions we are asked in Brock Hill
Can you work on a hospital site such as Mayflower Community Hospital?
Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Is a smaller place like Brock Hill outside your area?
No. Places such as Brock Hill are covered as much as the big towns. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
What guarantee comes with a mastic package?
Each package is backed by a 12-month guarantee. We are also fully insured for public liability.
What do you charge?
It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote.
What happens if old sealant might contain asbestos?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.
Will you come and look before quoting?
It depends on the job. Simple work can often be priced from photos, and bigger or more complex jobs normally get a visit.
Can you work plot by plot or floor by floor?
Working to your programme, we seal each area as it’s handed over. The sequence is agreed with the site manager at the start and updated as the programme moves.
What affects the price in Brock Hill
We price every job individually. The things that drive the figure:
- How much existing material needs removing
- Backing rod, priming and other preparation
- Phasing around occupants
- Travel to remote or island sites
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
Details that help us quote
For an accurate fixed quote, we need to understand the site. Useful things to include:
- What the building is and how it’s used
- How the joints are reached, and at what height
- Asbestos survey details if the building is older
- Your programme or deadline
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we will fill any gaps with a visit.
Keeping the joints sound
For the best life from the joints:
- Protect sealed areas from following trades
- Use the product the specification names
- Ask cleaners to use soft cloths around fresh sealant
- Get the mastic subcontractor involved early in the programme
Expect some settlement in the first months. Flexible sealants in the right joints handle normal movement. If that happens, let us know.
Sanitary joints that fail early become defects soon after occupation. Water gets behind trays, vanity tops and panels, leaving the remedial work to the contractor. Proper preparation, with the right silicone first time, keeps it off the defects list.
Building and refurbishing in Brock Hill
Brock Hill is in the South East, one of the UK’s drier regions. Winter mornings still bring frost and condensation on frames and panels, which is why external dates are agreed with the site manager. At about 28 miles from central London, Brock Hill is within reach of the capital. Towns within reach of London tend to keep building, from flats to offices and schools, and each scheme needs its mastic sealed to programme.
When a school such as Beauchamps High School is extended or refurbished, the mastic package is often squeezed into the holidays.

Site staff or a sealant specialist?
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
When something else is needed
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
- Joints damaged after sign-off by following trades
- Oversized gaps that need packing or adjustment by others
If you’re not sure, just call the office on 01277 525 020 or send details through our quote form and we will give you a straight answer before you book.
