Mastic sealing for commercial buildings in Four Throws
Different joints need different sealants. Low-modulus neutral-cure silicone suits many window perimeters and external movement joints, and MS polymer sealants stick well to many substrates and often take paint. We will confirm the colours available for the specified product. If you are dealing with communal area joints that look neglected and open joints in brickwork or panels, we can help, on communal entrances and stairwells, shopfronts below residential blocks and balcony and threshold joints alike. A single leaking joint is often how a building in Four Throws first comes to us: we look at the rest while we are there and tell you what we find.
Around smaller places like Four Throws, older walls fitted with newer windows are a familiar sight. Perimeter mastic there has to grip an uneven face and suit the building’s character.
We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application.

What sets the cost
A fixed quote reflects the actual work. It takes account of:
- Induction, permit and paperwork requirements
- Any access equipment needed
- Location, for remote and island sites
- How much existing material needs removing
Pricing mastic joints depends on quantities, condition and access, plus any specification you are working to. Ask us for a fixed quote.
Details that help us quote
A good diagnosis starts with the right details. Tell us:
- Whether the building will be occupied during the work
- Drawings or a marked-up plan, if available
- Any dates the work must fit around
- The asbestos register, for older buildings
To get a fixed quote, speak to us on 01277 525 020 or send details through our quote form with the site address and an outline of the work. You can also send details through our quote form.
When to bring in a specialist
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Diagnose, treat, sign off
Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. For work around Four Throws, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- A building-by-building inspection lists the failed joints.
- The quote is fixed and split as suits you.
- We agree the programme and dates with you.
- Old mastic is removed and the joint faces prepared.
- Joints are resealed and tooled.
- Each building is checked and signed off with the 12-month guarantee.
Getting the site ready
- Warn occupants and staff about the work
- Have the specification and drawings to hand
- Point out parking and an unloading spot
Getting a fixed quote
Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

What happens if it’s left?
Looking at mastic during planned maintenance costs little. Waiting until leaks appear means working under pressure and less choice about when. Converted and older buildings near places like Four Throws tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
The price depends on how many linear metres there are, what has to come out first and how the joints are reached. Call for a fixed quote once you have the details.

For owners and agents in Four Throws
Four Throws is in the South East, one of the UK’s drier regions. External mastic still waits for dry faces and the right temperature, and the sunniest, most exposed sides of a building usually need attention first. Four Throws lies roughly 42 miles out from central London. Managed blocks of flats are a big part of commuter-belt property; their frame mastic often ages block-wide.
Older buildings near Four Throws, from historic houses such as Great Dixter (to the south-east of Four Throws) to more modest stock, need compatible products when frames are resealed. Property owners at sites such as Hawkhurst Station Business Park, 2 miles north-west of Four Throws, can have mastic renewed between lettings.

Signs you need mastic sealing in Four Throws
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 and fails early.
Things that usually lead to an enquiry:
- Draught complaints from residents or tenants
- Damaged joints in communal entrances and corridors
- Cracked, hardened mastic round windows on a block
- Repeated reactive repairs to the same buildings
Trustees of buildings like Church of All Saints can bring frame and external mastic into a planned maintenance list.

Questions we’re asked in Four Throws
Do you cover business parks and estates near Four Throws, such as Hawkhurst Station Business Park?
Yes. We cover Four Throws and the area around it, including industrial estates, business parks and retail parks such as Hawkhurst Station Business Park. A few photographs and the unit address let us price the work.
Is Four Throws off your patch?
No. Small places get the same service as large ones. 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 weather delay the job?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
Which sealant will you use?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
How soon can the area be used again?
We’ll confirm how long the chosen product needs to cure.
How do I request a quote?
There are four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photos and a postcode.
Do you guarantee the mastic work?
A 12-month guarantee covers our work. It applies to our workmanship rather than damage or problems with the frames.
