Mastic sealing for commercial buildings in Frogmore

We are CHAS accredited and a Constructionline member, with public liability insurance. If you’re dealing with repeated reactive repairs to the same buildings and brittle perimeter mastic across a building, we can help. A single leaking joint is often how a building in Frogmore first comes to us: we look at the rest while we’re there and tell you what we find.
Places the size of Frogmore usually have some housing association stock, small blocks and mixed-use buildings. The mastic around their frames and external joints ages like anywhere else.

After the work
Keep the joints in good shape with a few simple steps:
- Ask residents or tenants to report leaks and draughts early
- Share your contractor requirements early
- Check the asbestos register before any old mastic is disturbed
- Make mastic part of routine maintenance checks
Where a paintable product was specified, it can be painted after curing. Silicone typically can’t be painted, so keep decorators off it unless told otherwise.
Joints on a building age together, so it pays to look at the whole elevation. A planned reseal saves repeated visits.
Diagnose, treat, sign off
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. What matters most for a job in Frogmore is a clear list of what needs doing, so send photos of each area. A fixed quote follows.
- We inspect the joints, building by building, and record what has failed and why.
- A fixed quote follows, split by block or building if that suits you.
- 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.
- 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.
What we need from you
- Flag any permit to work we will need
- Agree which areas must stay open
- Point out parking and an unloading spot
Getting a fixed quote
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we will arrange a site visit if anything is unclear.

Common problems we fix in Frogmore
Frames, panels and masonry expand and contract through the year, and the sealant takes up that movement. If the joint or the product wasn’t suited to the movement, it splits long before it should.
These are often picked up first by site or facilities staff:
- Open joints in brickwork or panels
- Mastic failing across several blocks on an estate
- Leaks at window and door perimeters
- Draughts at frames across a block
Site managers at schools like Frogmore Junior School can fit frame mastic into the summer works.

FAQs: Frogmore
Is Frogmore too far out for you?
Not at all. Frogmore is within our area. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
We manage a building near Sandhurst station. Can you help?
Yes, and several blocks can go on one quote. Give us the building’s details and say how residents are notified, and we’ll quote and plan to suit.
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Is mastic sealing guaranteed?
There is a 12-month guarantee on our workmanship, backed by public liability insurance.
How long before the joints can be used?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
What about access for upper-floor joints?
We talk through access for each building when we quote. Tell us the number of storeys and whether scaffold or other access is planned and we will confirm the approach in the quote.
What the job involves on each surface
Tenement and older buildings
Traditional buildings have joints that need a careful approach. The material either side of the joint shapes the product choice.
Estate-wide resealing programmes
Consistent products and colours across an estate make future maintenance simpler.
Blocks and managed buildings in Frogmore
Frogmore lies roughly 32 miles out from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres. Frogmore sits in one of the drier corners of the country, the South East. Even so, frame mastic only goes on in dry, workable conditions, and south- and west-facing elevations, which take the most sun and rain, often age first.
Landlords with units on estates such as The Meadows Business Park, 0.8 miles east of Frogmore, can bring frame, door and external mastic across several units into one programme. If you look after a block within reach of Sandhurst station, which lies north of Frogmore, frame and balcony mastic can be renewed on one programme.

Why it’s worth doing now in Frogmore
Reacting to every complaint means sending someone out block by block. Planned resealing covers a whole building or estate in one go, under a single quote and a single programme. Sealant hardens, cracks and loses grip with age, UV and movement. Renewing it in good time keeps the building weathertight.
The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a fixed quote when you are ready.
