Mastic sealing for East Garston sites

Mastic sealing in East Garston, done properly
In buildings from before 2000, some old mastics contain asbestos. We check the asbestos register or survey before any old sealant is cut out, and work stops for testing if there’s any doubt. We don’t remove asbestos-containing materials. If you’re dealing with damp patches beside frames and open joints in brickwork or panels, we can help, on balcony and threshold joints, shopfronts below residential blocks and window and door perimeters on blocks alike. Facilities teams, main contractors and managing agents in East Garston tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
For owners with a single building near East Garston, we plan to finish in one visit where possible. Photos of each elevation help us quote accurately.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Our process
On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, and the work typically takes one or more days per building, depending on the joint lengths and the access. Rural sites near East Garston may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll 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.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- Old sealant is stripped and each face prepared back to firm material.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Each building is checked on completion and the work carries our 12-month guarantee.
Preparing the site
- Send any specification or drawings in advance
- For older buildings, check the asbestos register before work
- Tell us your opening times and when work is allowed
Request a quote
Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

After the work
Regular inspection catches problems early. In particular:
- Keep a record of when each building was resealed
- Start inspections with the most exposed faces
- Plan resealing building by building rather than complaint by complaint
- Check sealant joints during planned building inspections
Where a paintable product was specified, it can be painted after curing. Non-paintable silicone shouldn’t be painted over unless told otherwise.
Planned resealing is easier to budget than emergency repairs. A programme can start with the worst buildings so spending is spread.

What else we do in East Garston
What sealant work can’t fix
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Leaks through the frame itself rather than the perimeter
- Materials that need asbestos testing before work
- Water coming in from the roof or rainwater goods
If in doubt, speak to us on 01277 525 020 or email a schedule or drawings and we’ll say what we think before you book.
Surfaces we seal
- Communal entrances and stairwells
- Balcony and threshold joints
- Communal kitchens and washrooms
- Shopfronts below residential blocks
- External wall and movement joints
- Window and door perimeters on blocks

Your questions answered
Is East Garston too small for you to travel to?
No. Places such as East Garston are covered as much as the big towns. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
Can one quote cover a number of our buildings near East Garston?
Yes. Portfolio-wide programmes are a regular request. Send the addresses and photos and we will give a fixed quote.
Do you check for asbestos in old sealant?
Asbestos removal isn’t part of our work. Anything suspect is tested before we carry on in line with the dutyholder’s asbestos management.
Can people stay in the building while you reseal?
Residents and tenants carry on as normal. We flag any areas that need internal access well before the dates so you can arrange it with occupiers.
How soon can the area be used again?
We’ll confirm how long the chosen product needs to cure.
What guarantee do you give on resealing?
Our workmanship carries a 12-month guarantee and we hold public liability insurance.
How long do sealant joints last?
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.
When to bring in a specialist
Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Block-wide mastic in East Garston
East Garston lies roughly 59 miles out from central London. Managed blocks of flats are a big part of commuter-belt property, and window and balcony mastic on them tends to age at the same rate. The South East is one of the drier parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and the sunniest, most exposed sides of a building usually need attention first.
Trustees of buildings like Church of All Saints can bring frame and external mastic into a planned maintenance list. For owners and agents with buildings in or around East Garston, block-wide mastic programmes deal with frames and external joints of the same age together.

What happens if it’s left?
Sealing over failed mastic looks tidy for a while. It won’t grip the old sealant and soon comes away. Full removal and proper preparation is what lasts. Around East Garston, it’s better to renew all the failing joints at once. Send photographs of each area and we will quote for the lot.
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.
