Block-wide mastic in Slaugham
The South East is one of the drier parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and the sunniest, most exposed sides of a building usually need attention first. Slaugham lies roughly 32 miles out from central London. Managed blocks of flats are a big part of commuter-belt property.
With historic buildings such as Tyes Place, 1.8 miles to the east of Slaugham, in the wider area, owners of older properties around Slaugham should expect mastic to need a product that suits old masonry. If you’re responsible for a building such as St Mary's Church, frame and door mastic needs the same attention as any other property.

Mastic sealing in Slaugham
Across Slaugham and the rest of West Sussex, we work the same way: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. Addresses, photographs of typical joints and a rough idea of quantities let us give a quick quote or we can visit. We work on communal entrances and stairwells, shopfronts below residential blocks and window and door perimeters on blocks, and the usual reasons a site gets in touch are draughts at frames across a block and failed external movement joints. One point of contact handles commercial sealant work in Slaugham from the first photos to the final walk-round, whether it’s one building or several.
Rural conversions near places like Slaugham often set modern frames into older stone, flint or brick. The mastic needs to suit an irregular masonry face and the look of the building.
Our workmanship is guaranteed for 12 months, in Slaugham as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Doing it in-house
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.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Why it’s worth doing now in Slaugham
Failed perimeter mastic lets cold air in around frames, and they often blame the windows. Resealing the perimeters is often the simpler fix when the frames themselves are sound. Converted and older buildings near places like Slaugham tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a quote once you have the details.

When to call us in Slaugham
Occasionally the substrate fails, not the sealant, such as crumbling render, brick arrises or frame edges. If the edges are unsound, we say so before quoting the sealing.
Any of the following is a good reason to get the joints checked over:
- Estate-wide sealant that is simply worn out
- Patchy repairs in mismatched sealant
- No planned programme for sealant
- Draughts at frames across a block
Site managers at schools like Warninglid Primary School can fit frame mastic into the summer works.
What your quote should include
- How the existing material will be dealt with
- The named product and why it was chosen
- Are they CHAS accredited or on Constructionline?
- Their approach to joint depth and backing
What the job involves on each surface
Tenement and older buildings
Traditional buildings have joints that need a careful approach. The material either side of the joint shapes the product choice.
Commercial and mixed-use buildings
Mixed-use buildings combine shops below with flats or offices above, so phasing has to suit both. We plan around the site hours and access windows you give us.
For managing agents and facilities managers
Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.
CHAS accredited and a Constructionline member, we’re straightforward to vet for your supplier list. We are fully insured, and our insurance certificate can go with the quote.
Slaugham: questions and answers
Do you take on block-wide or estate-wide mastic work in Slaugham?
Yes. Planned programmes across a building, block or estate are a core part of this service. Send the addresses and photographs and we’ll give a fixed quote.
We manage a building near Balcombe station. Can you help?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Send the address, photographs of the elevations and your access arrangements, and we will give a fixed quote.
Which sealant will you use?
A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Can you seal joints high up on a block?
It depends on the building. We agree access with you at quote stage so there are no surprises.
Can you take on resealing for a block portfolio?
Yes, that’s exactly who this service is for. Buildings are scheduled in turn with dates agreed in advance.
Is asbestos a concern with old mastic?
Some mastics in pre-2000 buildings contain asbestos. We ask for the asbestos register or survey before work starts, and if it’s suspected, work stops until it’s tested.
Do you work in Slaugham?
Yes. We cover Slaugham, and the simplest way to start is to call 01277 525 020 or email the details over.
From enquiry to sign-off
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work usually takes a day or two for a single block, longer for an estate programme, and our waste is bagged and taken away as we go. Jobs in and around smaller places like Slaugham are normally planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.
- We inspect the joints, building by building, and record what has failed and why.
- We send a fixed quote that sets out the joints, the products and the programme.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- Old sealant is stripped and each face prepared back to firm material.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
Before we start on site
- Flag any permit to work we’ll need
- Move anything stored against the joints
- Tell us your opening times and when work is allowed
