Keeping the joints sound
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Encourage occupiers to report problems at frames
- Plan resealing building by building rather than complaint by complaint
- Share the asbestos register when you send details
- Log resealing dates block by block
Encourage occupiers to report water or draughts at frames. A quick report keeps a small repair small.
One failed perimeter normally 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.
About our mastic sealing in Beacon's Bottom
On a residential block, the work happens around people’s lives. Dates, areas and the order of work are agreed with you in advance, giving you what you need to notify residents. Entrances and stairwells are kept in use throughout. If you are dealing with occupiers reporting cold air round windows and a mix of products and colours from past repairs, we can put it right, on communal entrances and stairwells, communal kitchens and washrooms and balcony and threshold joints alike. A single leaking joint is often how a building in Beacon's Bottom first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Owners and agents with buildings around smaller places such as Beacon's Bottom tend to manage small terraces of association properties, converted barns and commercial units. Mastic around frames and on external joints wears out in time, whatever the building.
We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Common problems we fix in Beacon's Bottom
Much failed sealant was laid on dirty, dusty or damp surfaces. Without clean, sound faces and a primer where the product needs one it comes away from one face.
Typical triggers for a call:
- Failed external movement joints
- Old repairs sealed over failed mastic
- Window mastic that has split and shrunk
- Damp patches beside frames
Historic properties like West Wycombe Park House (to the east of Beacon's Bottom) show the age of some local stock, where frame mastic must suit soft brick or stone.

On site: what to expect
When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work normally takes a day or two for a single block, longer for an estate programme. For work around Beacon's Bottom, we aim to finish in one visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.
- We inspect the joints, building by building, and record what has failed and why.
- We send a fixed quote that sets out the joints, the products and the programme.
- The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- We remove the old mastic completely and clean the joint faces back.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
What we need from you
- Send asbestos survey details if the building is pre-2000
- Point out parking and an unloading spot

Window and door perimeters on blocks

External movement joints

Common questions from Beacon's Bottom clients
Is a smaller place like Beacon's Bottom outside your area?

Can you work to our specification?

What will the job cost?
Each job is quoted on its own details. To get one, ring 01277 525 020 or send photos by email.
Is any job too small?
We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
When it isn’t the sealant
Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is one of these:
- Substrate edges that need repairing first
- Glazing that needs replacing
- Materials that need asbestos testing before work
If you are not sure, just call 01277 525 020 or send details through our quote form and we will give you a straight answer before you book.

Why it’s worth doing now in Beacon's Bottom
Looking at mastic during planned maintenance costs little. Leaving it until there’s a leak turns it into reactive work and less choice about when.
