We are a Constructionline member and CHAS accredited, and we carry public liability insurance. Most enquiries involve failed external movement joints and water getting in round frames after rain, across communal kitchens and washrooms, communal entrances and stairwells and external wall and movement joints. Whoever orders the work in West Malling, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.

How a job runs
Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. For a site in West Malling, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.
- Each block or building is walked and the failed joints recorded with the likely cause.
- You get a fixed quote, priced per building where that helps your budgeting.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- We remove the old mastic completely and clean the joint faces back.
- Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
- Each building is checked on completion and the work carries our 12-month guarantee.
What we need from you
- Move anything stored against the joints
- Flag any permit to work we’ll need

Advice
What happens if it’s left?
Failed perimeter mastic lets cold air in around frames, and they often blame the windows. In many cases, new perimeter sealant deals with it where the frames themselves are sound. Small buildings around West Malling suffer from failed joints as much as large ones. Early resealing avoids the damage that follows a leak.
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

FAQs: West Malling
Does your area include sites such as Kings Hill Business Park, near West Malling?
Yes. Estates, retail parks and business parks around West Malling, Kings Hill Business Park among them, are all within reach. To start, just ring 01277 525 020 or send photos by email with the unit, the joints involved and your access times.
Is West Malling too small for you to travel to?
Not at all. West Malling is within our area. London and every South East county are within our area. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
How do you choose the sealant?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
What’s the quickest route to a quote?
It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photographs and a postcode.
Do you take on small jobs?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
What do you charge?
It depends on the job: quantities, access, the product and any phasing. Call for a fixed quote.
When to bring in a specialist
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
What sealant work can’t fix
Before quoting, we check that sealant is the right answer. It won’t put right:
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Materials that need asbestos testing before work
- Glazing that needs replacing
If in doubt, phone 01277 525 020 or use the quote form and we’ll say what we think.
What we seal
- Balcony and threshold joints
- Communal entrances and stairwells
- Shopfronts below residential blocks
- Window and door perimeters on blocks
- External wall and movement joints
- Communal kitchens and washrooms
How the quote is worked out
A fixed quote reflects the actual work. It allows for:
- How much existing material needs removing
- How much there is to seal
- Backing rod, priming and other preparation
- Working within restricted access windows
The specified product makes a difference, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.
Before you send an enquiry
Diagnosis starts before we arrive. Let us know:
- The type of building and who uses it
- The product your specification calls for
- Drawings or a marked-up plan, if available
- Where the site is, with the postcode
To get a fixed quote, ring 01277 525 020 or send details through our quote form. You can also send details through our quote form.
Common problems we fix in West Malling
Frames, panels and masonry expand and contract through the year, and every joint has to stretch and squeeze with them. A joint that was too narrow, too thin or the wrong product can’t cope long before it should.
If one of these sounds familiar, it’s time for a closer look:
- No planned programme for sealant
- Worn sealant at communal door frames
- A mix of products and colours from past repairs
- Brittle perimeter mastic across a building
If you look after a block within reach of West Malling station (0.7 miles east of West Malling), frame and balcony mastic can be renewed on one programme.
What to look for in a quote
- Do they follow the manufacturer’s priming guidance?
- How they’ll work around occupants
- Are they CHAS accredited or on Constructionline?
- Whether old or failed sealant will be cut out, not overlaid
