Mastic sealing for commercial buildings in Breach
Most buildings come with mastic joints nobody has looked at since handover and it slowly wears out: window perimeters, door frames, external joints and communal junctions all rely on it. Once it cracks, hardens or comes away, draughts and water find a way in along with complaints. If you’re dealing with no planned programme for sealant and mastic failing across several blocks on an estate, we can help. A single leaking joint is often how a building in Breach first comes to us: we look at the rest while we are there and tell you what we find.
Rural conversions near places like Breach 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: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Diagnose, treat, sign off
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Rural sites near Breach may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.
- A building-by-building inspection lists the failed joints.
- You get a fixed quote, per block or for the whole programme.
- Dates and areas are agreed so occupiers can be told.
- Failed sealant is removed and the faces prepared.
- Joints are resealed and tooled.
- We check the finished work and confirm the guarantee.

What happens if it’s left?
Reacting to every complaint means sending someone out block by block. Planned resealing covers a whole building or estate in one go and is simpler to manage and budget. Around Breach, it’s better to renew all the failing joints at once, rather than one at a time. Send photographs of each area and we’ll quote for the lot.
There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.

Site staff or a sealant specialist?
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
For owners and agents in Breach
Breach sits close to the coast, within about 3 miles. For owners and agents with buildings near the sea, exposed elevations are where frame mastic fails first, and they deserve more regular inspection. At about 34 miles from central London, Breach is within reach of the capital. Managed blocks of flats are a big part of commuter-belt property.
Site managers at schools like Newington Church of England Primary School can fit frame mastic into the summer works. Churches, halls and community buildings such as Church of St Mary are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.

Breach: questions and answers
Is Breach too far out for you?
Not at all. Breach is within our area. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.
Does a coastal location like Breach affect which sealant is used?
It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
Can you quote from photos?
Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.
Do you seal on top of existing sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.
Which sealant will you use?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Do you check for asbestos in old sealant?
Some mastics in pre-2000 buildings contain asbestos. We check the asbestos register or survey before disturbing it, and if it’s suspected, work stops until it’s tested.
Surface by surface
Estate-wide resealing programmes
Consistent products and colours across an estate make future maintenance simpler and easier to manage.
Tenement and older buildings
Older mastic can contain asbestos, so we check the asbestos register or survey first. If it’s suspected, work stops until it’s tested.
After the work
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Prioritise elevations facing the weather
- Encourage occupiers to report problems at frames
- Share your contractor requirements early
- Have the asbestos survey to hand for older buildings
Keep records of when each building was resealed. It helps plan the next round and shows what was done.
One failed perimeter typically 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.
Do you need mastic sealing in Breach?
Communal entrances and corridors see a lot of wear, and low-level joints get damaged. Cleaning products add to the wear.
It’s worth sending us details if you spot any of the following:
- Old repairs sealed over failed mastic
- Damp patches beside frames
- Brittle perimeter mastic across a building
- Damaged joints in communal entrances and corridors
Property owners at sites such as Newington Industrial Estate (to the south of Breach) can have mastic renewed between lettings.
What your quote should include
- Health and safety accreditation such as CHAS
