Mastic sealing in Flansham, done properly
Different joints need different sealants. Low-modulus neutral-cure silicone suits many window perimeters and external movement joints, while hybrid polymer sealants grip many materials and are often paintable. We’ll confirm the colours available for the specified product. Site teams most often ask us about cracked, hardened mastic round windows on a block and estate-wide sealant that is simply worn out, across shopfronts below residential blocks, balcony and threshold joints and communal kitchens and washrooms. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Flansham is the same: the right product in a properly prepared joint.
For owners with a single building near Flansham, we plan to finish in one visit where possible. Send photographs of the frames and joints and we’ll give a fixed quote.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Blocks and managed buildings in Flansham
The sea is no more than about 2 miles from Flansham. On buildings near the shore, the side facing the weather typically needs its mastic renewed first, and they deserve more regular inspection. Rainfall across the South East, Flansham included, is lower than in many parts of the UK. External mastic still waits for dry faces and the right temperature, and the sunniest, most exposed sides of a building usually need attention first.
Site managers at schools like Bishop Tufnell CofE Primary School can fit frame mastic into the summer works. Blocks of flats and mixed-use buildings often cluster around stations such as Barnham station (1.9 miles north of Flansham) and their window and balcony mastic tends to age at the same rate across a building.
Flansham is about 2 miles north-east of Bognor Regis, in West Sussex. Anywhere in PO22, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee.

FAQs: Flansham
Is Flansham off your patch?
Not at all. Flansham is within our area. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Do you cover business parks and estates near Flansham, such as Southern Cross Trading Estate?
Yes. We cover Flansham and the area around it, including industrial estates, business parks and retail parks such as Southern Cross Trading Estate. A few photos and the unit address let us price the work.
Can you send RAMS and CSCS details before starting?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are CHAS accredited and a Constructionline member.
Can you plan resealing across several buildings?
Block-wide and estate programmes are common. The quote can be split however suits your budgeting.
Can weather delay the job?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.
What do you charge?
Every job gets its own fixed quote. To get one, phone 01277 525 020 or email a schedule or drawings.
What affects the price in Flansham
Quotes vary with the job. Expect it to depend on:
- The product specified
- Whether old sealant has to be cut out first
- Location, for remote and island sites
- Induction, permit and paperwork requirements
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we will explain how it’s made up.
Sending details for a quote
A few photos plus some basic facts will normally do. It helps to include:
- The product your specification calls for
- Asbestos survey details if the building is older
- When you need the work done
- Photos of the joints, close up and from further back
Need a figure for a tender or a budget? We will quote against your scope and drawings that you can work with. For a chat about it beforehand, give us a call on 01277 525 020 or use the quote form.
When to call us in Flansham
UV and rain age external sealant. The surface chalks, the body stiffens and cracks appear most of all on the sunniest and most exposed elevations.
Things that usually lead to an enquiry:
- Draught complaints from residents or tenants
- Worn sealant at communal door frames
- Brittle perimeter mastic across a building
- Open joints in brickwork or panels
If you’re responsible for a building such as Bilsham Chapel, frame and door mastic needs the same attention as any other property.
Comparing quotes
- Is the sealant right for the movement and the substrate?
- Do they follow the manufacturer’s priming guidance?
- Proof of insurance
- The terms of the workmanship guarantee
When it isn’t the sealant
Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is any of the following:
- Masonry that has broken away beside the joint
- Frames that are rotten, warped or broken
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
If in doubt, speak to us on 01277 525 020 or email us and we will say what we think before you book.

Diagnose, treat, sign off
Inspect, seal, sign off: that’s the shape of every visit.

If others near Flansham need work, visits can be combined. A fixed quote is given before anything starts.
- First we look at the mastic on each building and note what needs replacing.
- You get a fixed quote, priced per building where that helps your budgeting.
- The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- Failed mastic is removed and the faces taken back to sound, dry material.

How the job changes by surface
Window and door perimeters on blocks
Blocks have a mix of frame materials, so the grade we pick has to bond to frame and wall alike. We will confirm the colours available for the specified product.
Commercial and mixed-use buildings
Where retail and residential share a building the programme has to suit everyone. We plan around the site hours and access windows you give us.
Why it’s worth doing now in Flansham
Sealing over failed mastic looks tidy for a while. It doesn’t bond and typically fails within a short time. Cutting out and resealing properly does it once. For buildings around smaller places like Flansham, 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. Resealing early avoids that.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.
