How we handle mastic sealing in Boarshead
Owners and agents usually inherit a building’s mastic rather than choose it and it slowly wears out: it sits round windows and doors, along external joints and through communal areas. When it hardens, splits or pulls away, water and draughts follow along with complaints. If you’re dealing with a mix of products and colours from past repairs and damaged joints in communal entrances and corridors, we can help, on communal kitchens and washrooms, communal entrances and stairwells and external wall and movement joints alike. A specialist sealant contractor works differently from a general builder: in Boarshead, that means joint design, primers and backing rod as standard.
Rural conversions near places like Boarshead often set modern frames into older stone, flint or brick. Perimeter mastic there has to grip an uneven face and suit the building’s character.
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.

How a job runs
Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. For a building around Boarshead, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.
- First we look at the mastic on each building and note what needs replacing.
- We send a fixed quote that sets out the joints, the products and the programme.
- The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- We remove the old mastic completely and clean the joint faces back.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
Preparing the site
- Send your site hours and access windows
- Point out parking and an unloading spot
- Send any specification or drawings in advance
Quotes
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.
Related advice
Why deal with it now?
Looking at mastic during planned maintenance costs little. Waiting until leaks appear means working under pressure with less control over timing. One visit to deal with every failing joint makes more sense than several trips to a place like Boarshead, rather than one at a time. Photos of every joint help us quote for the whole job.
There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

Common questions from Boarshead clients
We manage a building near Eridge station. Can you help?
Yes. Blocks of any size are within what we do. Give us the building’s details and say how residents are notified, and we’ll quote and plan to suit.
Is Crowborough Business Park, near Boarshead, within your area?
Yes. Our area takes in Boarshead and its surroundings, with estates and business parks such as Crowborough Business Park included. Send details of the unit and the work through our quote form for a quick quote.
How do you reach windows on upper floors?
Access is discussed and agreed before the quote is fixed. Tell us the number of storeys and whether scaffold or other access is planned, and we’ll tell you how we’d approach it.
How long does a job like this take?
That varies with the scale of the job, though a typical visit usually takes a day or two for a single block, longer for an estate programme. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Is asbestos a concern with old mastic?
In older buildings, old mastic can contain asbestos. We ask for the asbestos register or survey before work starts, and if it’s suspected, work stops until it’s tested.
Can you take on resealing for a block portfolio?
Yes. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords, and we quote building by building or as a programme.
Can you plan resealing across several buildings?
We can. Each building is inspected, quoted and scheduled in turn, and the programme can start with the worst.
Cost factors for mastic joints
We price every job individually. The things that drive the figure:
- Joint width, depth and condition
- Phasing around occupants
- How much there is to seal
- How much existing material needs removing
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 when you’re ready.
Details that help us quote
Whether it’s one area or a whole building, the same details help:
- The type of building and who uses it
- A wide shot and a close-up of the area
- The site address and postcode
- Any dates the work must fit around
Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. The easiest way is to speak to us on 01277 525 020 or email a schedule or drawings.
Do you need mastic sealing in Boarshead?
Poor preparation explains many failed joints. Where the faces weren’t cleaned or primed as specified, the bead peels off one side.
Things that typically lead to an enquiry:
- Occupiers reporting cold air round windows
- Water getting in round frames after rain
- No planned programme for sealant
- A mix of products and colours from past repairs
Historic properties like Groombridge Place, 3.3 miles to the north of Boarshead, show the age of some local stock, where frame mastic must suit soft brick or stone.
Before you book anyone
- How the joint faces will be prepared and primed
- Which product they’ll use, and why it suits the joint
- Their pre-qualification and accreditations
- Can the work be phased to keep areas open?
Maintenance after handover
Regular inspection catches problems early. Specifically:
- Keep bins and bikes away from communal door frames
- Avoid piecemeal callouts where you can
- Encourage occupiers to report problems at frames
- List the paperwork your organisation requires when you send details
Include sealant in planned building inspections. Check for splits, open joints, brittle mastic and lifting edges and record where they are.
One failed perimeter normally means others on the same building are close, so it pays to look at the whole elevation. Doing them together saves going back again and again.
How the job changes by surface
Communal areas
Joints at low level in communal areas take knocks from bins, bikes and buggies, so they often need renewing sooner.
External movement joints
The joint width has to suit the movement and the sealant’s capability with the width-to-depth ratio set as the manufacturer advises.
Mastic sealing around Boarshead: how the place shapes the job
Boarshead sits in one of the drier corners of the country, the South East. External mastic still waits for dry faces and the right temperature, and the sunniest, most exposed sides of a building usually need attention first. At about 32 miles from central London, Boarshead is within reach of the capital. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres, and window and balcony mastic on them tends to age at the same rate.
If your remit includes a building such as Beacon Academy, frame and door mastic can be programmed for the holidays. Landlords with units on estates such as Crowborough Business Park, 1.1 miles south-west of Boarshead, can bring frame, door and external mastic across several units into one programme.
