Mastic sealing across Wineham
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
Doing it in-house
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Certain joints really need a specialist: 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.
Mastic sealing in Wineham, done properly
Treatment starts with a proper look: 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, with backing rod setting the depth where it’s needed. Most enquiries involve draught complaints from residents or tenants and cracked, hardened mastic round windows on a block, across communal entrances and stairwells, window and door perimeters on blocks and external wall and movement joints. Facilities teams, main contractors and managing agents in Wineham tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Rural conversions near places like Wineham 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 behind the joints we seal with a 12-month guarantee. That covers our preparation and application.

Looking after the joints
Once the work is signed off, these steps help:
- List the paperwork your organisation requires when you send details
- Check the asbestos register before any old mastic is disturbed
- Keep bins and bikes away from communal door frames
- Ask residents or tenants to report leaks and draughts early
Add mastic joints to your cyclical inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away, and note the building and elevation.
Leaks at window perimeters spoil finishes and can affect frames. Resealing early keeps the job small.
Cost factors for mastic joints
These are the things that shape the price:
- Which sealant the job calls for
- The total length or number of joints
- Any access equipment needed
- Location, for remote and island sites
Pricing mastic joints depends on how many there are, their condition and the access. Call for a quote.

Wineham: questions and answers
Does your area include sites such as Oakendene Industrial Estate, near Wineham?
Yes, sites like Oakendene Industrial Estate are within our area, along with the rest of Wineham. To start, just give us a call on 01277 525 020 or use the quote form with the unit, the joints involved and your access times.
Do you take on block-wide or estate-wide mastic work in Wineham?
Yes. Portfolio-wide programmes are a regular request. Send the addresses and photographs and we’ll give a fixed quote.
How long does a job like this take?
The duration is planned around your programme and the access we are given. We will give you an estimate of time on site when we quote.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and we will price the work to it, flagging anything that needs clarifying.
When is resealing likely to be due?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
What guarantee do you give on resealing?
Our workmanship carries a 12-month guarantee, backed by public liability insurance.
When to call us in Wineham
Sunlight and weather break mastic down over time. It stiffens, stops stretching and cracks, especially on south and west faces.
Typical triggers for a call:
- Damaged joints in communal entrances and corridors
- Patchy repairs in mismatched sealant
- Failed external movement joints
- Complaints coming in block by block
Churches, halls and community buildings such as The Parish Church of St Peter are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.

- Will CSCS-carded applicators be on site?
- Their pre-qualification and accreditations
- Can the work be phased to keep areas open?
Frames, entrances and external joints in Wineham
Wineham is about 37 miles from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres. The South East is one of the drier parts of the UK. Outside work still depends on dry joints, and the sunniest, most exposed sides of a building typically need attention first.
For owners of several units at places like Oakendene Industrial Estate, 1.3 miles to the north-west of Wineham, one programme can deal with frame and external mastic across the lot. With historic buildings such as Ockenden Manor, 4.9 miles to the north-east of Wineham, in the wider area, owners of older properties around Wineham should expect mastic to need a product that suits old masonry.

When it isn’t the sealant
We check first that sealant really is the fix. It isn’t the answer for:
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Failed window or door frames, which need a window contractor
- Broken glass or failed sealed units
Not sure which it is? You can call the office on 01277 525 020 or send photos by email and we’ll tell you honestly.

- 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.
- Failed mastic is removed and the faces taken back to sound, dry material.
- Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
