Mastic sealing for businesses in Farleigh
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
How the quote is worked out
To price the job, we consider:
- Whether the work must be split into stages
- Quantities, in metres or numbers
- Access and working height
- How much existing material needs removing
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we will price your job on its own details.
What to include in your enquiry
It doesn’t need to be a full survey. These details are enough to start:
- Whether the building will be occupied during the work
- The site address and postcode
- Drawings or a marked-up plan, if available
- Anything awkward about access or site hours
Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

We are a Constructionline member and CHAS accredited, and we carry public liability insurance.

When it isn’t the sealant
Honesty saves time and money. New sealant won’t cure:
- Misted or failed double-glazed units
- Failed window or door frames, which need a window contractor
- Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
If in doubt, speak to us on 01277 525 020 or email drawings and photos and we will say what we think before you book.
What we seal

What the job involves on each surface
Estate-wide resealing programmes
A programme can start with the worst buildings and work down. You get one fixed quote per building or for the whole estate.
Window and door perimeters on blocks
Frames vary from uPVC to aluminium and timber, and the product is matched to the frame material and the masonry. We’ll confirm the colours available for the specified product.
Aftercare for building managers
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Avoid piecemeal callouts where you can
- Log resealing dates block by block
- Encourage occupiers to report problems at frames
- Check the asbestos register before any old mastic is disturbed
Protect entrance and corridor joints from knocks where possible. Damage at low level is the most common reason communal joints fail early.
Budgets are easier to plan when sealant is part of planned maintenance. A programme can start with the worst buildings and work down the list.

Block-wide mastic in Farleigh
Rainfall across the South East, Farleigh included, is lower than in many parts of the UK. Outside mastic still needs a dry joint and the right temperature, while the elevations that take the most sun tend to show hardened mastic first. Farleigh lies roughly 12 miles out from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres; their frame mastic often ages block-wide.
Blocks of flats and mixed-use buildings often cluster around stations such as Upper Warlingham station (2.3 miles south-west of Farleigh) and their window and balcony mastic tends to age at the same rate across a building. If you own or manage units on a site such as Vulcan Way Industrial Estate (1.7 miles north-east of Farleigh), failed mastic on frames, door surrounds and external joints can be dealt with unit by unit. Schools and community buildings such as Meridian High School need frame and external mastic kept sound like any building.
Farleigh is about 4 miles north-east of Caterham, in Surrey.

Common questions from Farleigh clients
Is Farleigh off your patch?
No. Places such as Farleigh are covered as much as the big towns. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.
Will you take on work at estates like Vulcan Way Industrial Estate, close to Farleigh?
Yes. We cover Farleigh and the area around it, including industrial estates, business parks and retail parks such as Vulcan Way Industrial Estate. To start, just call the office on 01277 525 020 or email us with the unit, the joints involved and your access times.
What do you charge?
That depends on the job: quantities, access, the product and any phasing. Call for a quote.
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.
Do you need to see the site first?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.
Will you quote for a small job?
Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.
Does the weather affect the work?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
