How we handle mastic sealing in Granborough
Older blocks and commercial buildings can have mastic that contains asbestos. We check the asbestos register or survey before any old sealant is cut out and if it’s suspected, work stops until it’s tested. We don’t remove asbestos-containing materials. We work on communal kitchens and washrooms, communal entrances and stairwells and window and door perimeters on blocks, and the failures we are asked to look at most are brittle perimeter mastic across a building and complaints coming in block by block. One point of contact handles commercial sealant work in Granborough from the first photographs to the final walk-round, whether it’s one building or several.
For owners with a single building near Granborough, we plan to finish in one visit where possible. Photos of each elevation help us quote accurately.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

Common questions from Granborough clients
Is Granborough too small for you to travel to?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.
Do you cover business parks and estates near Granborough, such as Station Road Industrial Estate?
Yes. We cover Granborough and the area around it, including industrial estates, business parks and retail parks such as Station Road Industrial Estate. To start, just phone 01277 525 020 or email us with the unit, the joints involved and your access times.
Will residents or tenants be disturbed?
We plan around people living or working in the building. We agree the programme so you can notify occupiers, and entrances stay in use.
Do you do block-wide mastic programmes?
Yes. Each building is inspected, quoted and scheduled in turn starting wherever is most urgent.
Do you guarantee the mastic work?
A 12-month guarantee covers our work. It covers our workmanship, not later building movement, damage or frame failures.
Can weather delay the job?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
How long does a typical visit take?
That varies with the scale of the job, though a typical visit usually takes one or more days per building, depending on the joint lengths and the access. For bigger or phased jobs, we’ll set out a timescale with the quote.

For owners and agents in Granborough
Granborough is in the South East, one of the UK’s drier regions. Outside mastic still needs a dry joint and the right temperature, and the sunniest, most exposed sides of a building usually need attention first. Granborough is about 45 miles from central London. Managed blocks of flats are a big part of commuter-belt property.
For owners of several units at places like Station Road Industrial Estate, 2 miles north of Granborough, one programme can deal with frame and external mastic across the lot. For a school such as Sir Thomas Fremantle School, perimeter mastic on windows and doors is a holiday job. Older buildings near Granborough, from historic houses such as Claydon House, 2.9 miles west of Granborough, to more modest stock, need compatible products when frames are resealed.

For managing agents and facilities managers
Building owners and managing agents use us on everything from one building to a spread of sites around Granborough. One quote can cover more than one site, which keeps the paperwork simple.
Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.
What we can’t put right
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Materials that need asbestos testing before work
- Glazing that needs replacing
- Roof leaks, gutters or failed flashings that aren’t sealant joints
Not sure which it is? You can speak to us on 01277 525 020 or email a schedule or drawings and we will tell you honestly.
What we seal
- Communal entrances and stairwells
- Window and door perimeters on blocks
- Shopfronts below residential blocks
- External wall and movement joints
- Balcony and threshold joints
- Communal kitchens and washrooms
Leave it or put it right?
A bead run over old mastic can look like a repair. It doesn’t bond and usually fails within a short time. Cutting out and resealing properly does it once. Halls, stores and units around places like Granborough may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
What a job costs comes down to the quantity of joints, what has to come out first and how the joints are reached. Call for a quote once you have the details.

What affects the price in Granborough
These are the things that shape the price:
- The total length or number of joints
- Travel to remote or island sites
- Which sealant the job calls for
- The size and state of each joint
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
What we need to price the job
The more we know, the firmer the quote. When you get in touch, include:
- Photos of the joints, close up and from further back
- The postcode of the building
- How the joints are reached, and at what height
- Asbestos survey details if the building is older
Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.
Keeping the joints sound
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:
- Group repairs into a planned programme
- Reduce knocks to communal area joints
- Encourage occupiers to report problems at frames
- Include mastic in your cyclical inspections
Where a paintable product was specified, it can be painted after curing. Silicone normally can’t be painted, so keep decorators off it.
Water getting in round frames can damage plaster, decoration and the frames themselves. Early resealing is far simpler than repairs inside.
