About our mastic sealing in Groombridge
We diagnose before we prescribe: which joints have failed, why, and whether sealant is the right answer. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in and backing rod used wherever a joint is deep. If you have leaks at window and door perimeters and draughts at frames across a block, we can help. One point of contact handles commercial sealant work in Groombridge from the first photos to the final walk-round, for single jobs and planned programmes alike.
Rural conversions near places like Groombridge 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.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

What sets the cost
There’s no standard rate for sealant work, since sites vary so much. What we look at:
- The total length or number of joints
- How much existing material needs removing
- Access and working height
- Whether the work must be split into stages
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.
What we need to price the job
We can often quote from photographs and a few details. It helps to include:
- Whether the building will be occupied during the work
- Specification clauses that apply
- When you need the work done
- The asbestos register, for older buildings
Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.
For managing agents and facilities managers
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Groombridge can sit alongside others in a wider programme.
Groombridge: questions and answers
Will you take on a block within reach of Eridge station?
Yes, and several blocks can go on one quote. Send the address, photos of the elevations and your access arrangements, and we’ll give a fixed quote.
Is Groombridge too small for you to travel to?
Not at all. Groombridge is within our area. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
Can people stay in the building while you reseal?
The work is planned around occupiers. Dates and areas are agreed with you so residents or tenants can be told and communal access is kept open.
Is mastic sealing guaranteed?
Every building we reseal has a 12-month guarantee. It applies to our workmanship rather than damage or problems with the frames.
Is asbestos a concern with old mastic?
In older buildings, old mastic can contain asbestos. We check the asbestos register or survey before disturbing it, and if it’s suspected, work stops until it’s tested.
Is it fine to apply new sealant on top of old?
No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
How long does a typical visit take?
The duration is planned around your programme and the access we’re given. You’ll have an expected duration with the quote.
Looking after the joints
For the best life from the joints:
- Keep a record of when each building was resealed
- Look at the sunniest and most exposed elevations first
- Protect low-level joints in entrances
- Group repairs into a planned programme
Our workmanship is covered for 12 months, so report any failure in that time. After that, regular inspection keeps the programme on track.
Joints on a building age together so a single failure is a sign to check the rest. Doing them together saves going back again and again.
On site: what to expect
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed before we move to the next. Rural sites near Groombridge may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.
- We check the asbestos register for older buildings and look at the joints.
- A fixed quote covers the joints, products and order of work.
- Failed mastic is removed completely.
- Joint faces are cleaned, backed and resealed.
- Buildings are completed in turn.
Before we start on site
- Flag any permit to work we’ll need
- Tell staff and tenants when we’ll be in
- Arrange parking or a loading space
Getting a fixed quote
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.
Advice
Why deal with it now?
Open external joints let water into walls and around frames. That can lead to damp, staining and damage to finishes, which is harder to deal with than resealing. Halls, stores and units around places like Groombridge may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Blocks and managed buildings in Groombridge
At about 29 miles from central London, Groombridge is within reach of the capital. Managed blocks of flats are a big part of commuter-belt property; their frame mastic often ages block-wide. The South East is one of the drier parts of the UK. External mastic still waits for dry faces and the right temperature, and the sunniest, most exposed sides of a building normally need attention first.
If you own or manage units on a site such as Speldhurst Business Park, 2.7 miles north-east of Groombridge, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit. Schools and community buildings such as Groombridge St Thomas' Church of England Primary School need frame and external mastic kept sound like any building.

Common problems we fix in Groombridge
Poor preparation explains many failed joints. Where the faces weren’t cleaned or primed as specified it comes away from one face.
Common reasons buildings call us in:
- Old repairs sealed over failed mastic
- Damaged joints in communal entrances and corridors
- No planned programme for sealant
- Failed external movement joints
Blocks of flats and mixed-use buildings often cluster around stations such as Eridge station, 1.8 miles south-east of Groombridge, and their window and balcony mastic tends to age at the same rate across a building.
