Construction mastic in Sulham, done properly
On a new build, the mastic package is one of the last trades through each area, which puts it right on the critical path. Mastic Doctor takes on mastic packages for main contractors and developers. We work on sanitary and kitchen joints, cladding and panel joints and floor and skirting junctions, and what we’re called in for most is new external sealant already peeling away and sealant knocked or painted over by other trades. Whoever orders the work in Sulham, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.
Construction in and around smaller places such as Sulham 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.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Keeping the joints sound
Problems stay small when the joints are checked regularly. In particular:
- Brief the final clean team to avoid blades near sealant
- Don’t schedule sealing before decorators and flooring are done
- Brief following trades on areas that have been sealed
- Share drawings and the specification as soon as possible
A new structure shifts as it loses construction moisture. Flexible sealants in the right joints handle normal movement. We can advise if a joint needs a different product.
External joints sealed in poor weather are a common cause of early failure. Holding off until conditions suit avoids callbacks.
Cost factors for mastic packages
Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:
- How much existing material needs removing
- The total length or number of joints
- Travel to remote or island sites
- Whether the work must be split into stages
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we’ll explain how it’s made up.
Before you send an enquiry
There’s no need for a formal survey. These details are enough to start:
- The site address and postcode
- Clear photographs of the problem areas
- Access details, including height
- The type of building and who uses it
For a fixed quote, call 01277 525 020 or email drawings and photos, telling us the site location and the nature of the job. Our quote form is another easy route.
When something else is needed
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Oversized gaps that need packing or adjustment by others
- Joint design decisions that belong to the architect or engineer
- Joints damaged after sign-off by following trades
Not sure which it is? You can call 01277 525 020 or use the quote form and we’ll tell you honestly before you book.

Your questions answered
Can work at a site such as University of Reading fit around teaching?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Is Sulham too small for you to travel to?
No. Small places get the same service as large ones. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
How many days will you need on site?
It depends on the scope, but the work usually takes whatever the programme allows, since the work follows the trades as areas are released. Larger or phased jobs take longer, and we will give you a timescale with the quote.
When is resealing likely to be due?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Can you work plot by plot or floor by floor?
We follow the trades through the building. Each plot, floor or elevation is sealed when it’s ready, and we will raise anything that holds the work up.
Can you clear a mastic snag list before handover?
Yes. Snag-only work is something we take on and damaged joints are redone properly.
What’s the quickest route to a quote?
There are four steps: send details, get a quote, we seal, guaranteed. The first step only needs photographs and a postcode.
Building and refurbishing in Sulham
Central London is about 42 miles from Sulham. Towns within reach of London tend to keep building, from flats to offices and schools, and main contractors there need mastic that keeps to the programme. Sulham sits in one of the drier corners of the country, the South East. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so we time external mastic for dry faces and agree it with the site team.
When a college such as Integration College, 1.8 miles to the south-east of Sulham, builds or refurbishes, the mastic package normally has to fit around students and staff. On a campus such as University of Reading (5 miles east of Sulham), new teaching buildings and residences are usually built and refurbished around the academic year. Recladding or extending a unit at a site like Turnhams Green Business Park (to the south of Sulham) brings panel joints and frame perimeters into the programme.

Related advice
Site staff or a sealant specialist?
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
