Construction mastic in West Street
The specification and the programme set the job rather than whatever product is to hand. Where the specification names a product, we use it, and if an alternative is proposed, it goes to you for acceptance first. Backing, primer and depth follow what the sealant maker sets out so the detail on the drawing is what ends up on site. If you have early adhesion failures on new external joints and window and door perimeters that won’t pass inspection, we can put it right, whatever the surface. A specialist sealant contractor works differently from a general builder: in West Street, that means joint design, primers and backing rod as standard.
Around smaller places like West Street, 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. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Looking after the joints
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Use the product the specification names
- Release areas for mastic once other trades have finished in them
- Record the products used in the O&M file
- Ask installers to correct oversized gaps first
Record which products went where in the handover file. That helps the building owner maintain the joints later and avoids guesswork when joints are renewed. Tell us what records you need and we will confirm with the quote.
External joints sealed in poor weather are a common cause of early failure. Holding off until conditions suit avoids callbacks.
From enquiry to sign-off
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then handed back before we move to the next.

Doing it in-house
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.
What we can’t put right
We check first that sealant really is the fix. It isn’t the answer for:
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Frames fitted out of tolerance
- Approving fire stopping as compliant
If you’re not sure, just speak to us on 01277 525 020 or email the details over and we will give you a straight answer before you book.
What we seal
- Floor and skirting junctions
- Internal decorators’ caulk
- Cladding and panel joints
- Window and door perimeters
- Brick and block movement joints
- Sanitary and kitchen joints
Mastic packages on West Street sites
The South East is one of the drier parts of the UK. Winter mornings still bring frost and condensation on frames and panels, which is why external dates are agreed with the site manager. West Street is about 39 miles from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and main contractors there need mastic that keeps to the programme.
For contractors refurbishing units at places like Roebuck Business Park, which lies west of West Street, the mastic covers cladding panels, roller-door and window perimeters. When a school such as The Lenham School is extended or refurbished, the mastic package is often squeezed into the holidays.
West Street is about 6 miles south of Sittingbourne, in Kent. If you are looking for construction mastic in West Street, we can help, as we do across Kent. We work across 931 places in Kent. Sites around London have their own page, roughly 39 miles from West Street.

What we’re called out for in West Street
Most mastic snags on new buildings come from sequencing rather than product. Sealing before decorators, flooring or other trades have finished leaves joints exposed to damage.
Common reasons buildings call us in:
- Failed sealant in an existing building being refurbished
- Cracks opening in caulked internal joints
- Early adhesion failures on new external joints
- Sealant knocked or painted over by other trades
Older buildings in the area around West Street, such as Leeds Castle, which lies west of West Street, need care when sealed: the product has to suit soft or historic materials.
What to look for in a quote
- Which product they’ll use, and why it suits the joint
- How joint depth will be controlled
- How they’ll work around occupants
- Their pre-qualification and accreditations
Your questions answered
Will you take on work at estates like Roebuck Business Park, close to West Street?
Yes. Estates, retail parks and business parks around West Street, Roebuck Business Park among them, are all within reach. A few photographs and the unit address let us price the work.
Will you plan work around the academic year at somewhere like Canterbury Christ Church University?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Can you come in just for snagging?
Yes, we can. Share the list and photos, and a fixed quote follows, then clear it to your programme.
Do you use the sealant named in the specification?
The specified product is what goes in. If we think an alternative would suit better, we put it to you first.
Do you do fire-rated sealing on new builds?
Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the manufacturer’s tested details. The design and sign-off belong to the designer, fire engineer or building control.
How do you deal with asbestos in old sealant?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.
Can the sealant be colour-matched?
Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We will confirm the colours available for the specified product.
What sets the cost
Before we quote, we look at:
- Removal of failed or old sealant
- The total length or number of joints
- Backing rod, priming and other preparation
- Working within restricted access windows
The product called for affects the cost, and so does the preparation. Access, phasing and site rules also count.
Before you send an enquiry
To price the job accurately, we need a clear picture of the site. Send us:
- When you need the work done
- The postcode of the building
- Photos of the joints, close up and from further back
- The type of building and who uses it
