Signs you need construction mastic in Petham
Frames installed with uneven gaps make perimeter sealing harder. Every product has limits on how wide a joint it can bridge. We flag them early rather than filling them with sealant that won’t last.
Look out for the following:
- Frame perimeters left unsealed or poorly sealed
- Snag items on joints that need redoing before handover
- External joints sealed in damp or cold conditions that are now failing
- Frame gaps too wide for sealant alone
Building work at universities like University of the Creative Arts, 4 miles north-east of Petham, is often timed for the summer, mastic included.
What your quote should include
- What site paperwork they can supply
- Can the work be phased to keep areas open?
- Will CSCS-carded applicators be on site?
- Are they CHAS accredited or on Constructionline?
About our construction mastic in Petham
Most of the packages we price run well beyond frames: external door and window perimeters, internal decorators’ caulk where specified, sanitary joints in bathrooms and washrooms, kitchen worktops and splashbacks, and snagging before handover. Splitting those between trades often leaves gaps in responsibility, and one applicator team gives a consistent finish. Site teams most often ask us about different trades sealing to different standards and perimeter gaps outside the sealant’s range, across brick and block movement joints, internal decorators’ caulk and cladding and panel joints. Searching for sealant specialists in Petham? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
Construction in and around smaller places such as Petham is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Surface by surface
Bathrooms, en suites and washrooms
In bathrooms and washrooms, an anti-mould sanitary silicone goes around every fitting. Each joint is prepared, sealed and finished with a neat tooled line.
Kitchens and utility areas
On commercial kitchen fit-outs, hygienic sealants are often specified. We follow the specification and seal to a smooth, cleanable finish.
After the work
Keep the joints in good shape with a few simple steps:
- Keep finished joints away from paint, plaster and scrapers
- Record the products used in the O&M file
- Stick to the specified sealant rather than a generic substitute
- Share drawings and the specification as soon as possible
After we have sealed an area, it helps to keep other trades from damaging the joints. New beads should be left to cure before cleaning or decorating nearby; we confirm the time for each product.
In wet areas, a weak sanitary joint shows up quickly once the building is occupied. Leaks behind showers and basins damage finishes and floors, and the repair falls into the defects period. Getting the product and preparation right first time avoids that.
What we can’t put right
Not every problem is a sealant problem, and we’re upfront when that’s the case. These need a different solution:
- Joint design decisions that belong to the architect or engineer
- Damage to finishes by other trades after we’ve sealed
- Frames fitted out of tolerance
If in doubt, call the office on 01277 525 020 or email the details over and we’ll say what we think before you book.
What we seal
- Brick and block movement joints
- Cladding and panel joints

Cost factors for mastic packages
There’s no standard rate for sealant work, because every site is different. What we look at:
- Specialist products, such as fire-rated or hygienic sealants
- How much there is to seal
- Phasing around occupants
- How accessible the joints are
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.
Sending details for a quote
There’s no need for a formal survey. These details are enough to start:
- Drawings or a marked-up plan, if available
- Your programme or deadline
- Photos of the joints, close up and from further back
- Access details, including height
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.
Questions we are asked in Petham
Can you work at a site such as Stour Valley Business Park, by Petham?
Yes, sites like Stour Valley Business Park are within our area, along with the rest of Petham. To start, just phone 01277 525 020 or email the details over with the unit, the joints involved and your access times.
Can you work on a hospital site such as Kent and Canterbury Hospital?
Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Is any job too small?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
What happens if the weather stops external sealing?
Conditions have to suit the product before external work starts. Wet or cold joints cause adhesion problems so it’s better to wait.
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, and we confirm it before leaving site.
Will you stick to the specified products?
Specification first, then the maker’s instructions. Primers, backing and joint depth follow what the manufacturer sets out.
Who decides which product is used?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, which is why external dates are agreed with the site manager.
