About our facade sealing in Westbourne
Every facade quote starts with how the joints will be reached. Let us know what access exists or is planned, and any site rules we need to work around, and we will fit the work around it. If you are dealing with perimeter sealant that has split or peeled away and weathered joints at frame-to-structure perimeters, we can help. Searching for sealant specialists in Westbourne? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
Around smaller places like Westbourne, building work normally means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
A 12-month guarantee applies to all our work in West Sussex. If an installation problem shows up, call 01277 525 020 or email us and we’ll arrange a return visit.

Why deal with it now?
Patch repairs over old sealant tend to come back. A full cut-out and fresh bead is the repair that holds. For buildings around smaller places like Westbourne, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Should maintenance staff do it?
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with 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.
Quoting for work in Westbourne
Quotes vary with the job. Expect it to depend on:
- Which sealant the job calls for
- Removal of failed or old sealant
- How much there is to seal
- Travel to remote or island sites
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.
What to include in your enquiry
Good information means a firmer quote. Helpful details to send:
- Whether the building will be occupied during the work
- Where the site is, with the postcode
- Any dates the work must fit around
- Anything awkward about access or site hours
Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.
When something else is needed
A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is any of the following:
- Replacing glass or failed glazing units
- Water getting in through cracked render or porous masonry
- Movement beyond what any sealant can handle
If in doubt, call the office on 01277 525 020 or email us and we’ll say what we think before you book.

FAQs: Westbourne
Our building in Westbourne is near the coast: does that change the sealant?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
Is Westbourne too small for you to travel to?
No. Places such as Westbourne are covered as much as the big towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
Can you work while the building is occupied?
Yes, with some planning. Tell us your site hours and access windows and we’ll plan around them.
Will you quote for a small job?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
Is your workmanship covered by a guarantee?
Yes. Workmanship is guaranteed for 12 months.
Which sealant will you use?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Can the sealant be colour-matched?
In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We’ll confirm the colours available for the specified product.
Our process
At the end of each section, we remove the tape, clean down and inspect every joint. If an area should be left alone while the sealant cures, we say how long and put signs out. Smaller jobs around Westbourne can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.
- First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
- Failed sealant is cut out along its full length.
- Both faces are cleaned and, where the product needs it, primed.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- The completed runs are checked with you, then the 12-month guarantee applies.
Preparing the site
- Tell us your opening times and when work is allowed
- Make sure the joints can be reached
- Point out any areas we must not close

Keeping the joints sound
Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:
- Plan facade sealing alongside redecoration
- Clear debris that holds water against joints
- Walk the elevations once or twice a year
- Record the product and colour used on each elevation
After heavy weather, check vulnerable elevations for signs of water inside. Catching a new leak early keeps the repair small.
Building facade joints into a maintenance cycle avoids emergency repairs. Regular checks let you renew joints before water gets in.
Building and refurbishing in Westbourne
Westbourne lies within about 2 miles of the sea. Coastal exposure means perimeter and cladding joints work harder than on an inland job, so we check the specified product suits the exposure before the first bead. Westbourne lies roughly 57 miles out from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and each scheme needs its mastic sealed to programme.
For contractors at a school such as Westbourne Primary School, sealing has to be finished before term starts. Units on estates such as Hambrook Business Park, 2 miles to the east of Westbourne, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. New wings at hospitals like Spire Hospital Portsmouth (to the west of Westbourne) bring long runs of window and panel joints to seal.
