Photos, a specification or a quick description of the joints is enough to start a fixed quote.
How we handle mastic sealing in Claygate Cross
There isn’t one mastic for every joint on a building. Low-modulus neutral-cure silicone suits many window perimeters and external movement joints, and MS polymer sealants stick well to many substrates and often take paint. We will confirm the colours available for the specified product. We work on balcony and threshold joints, communal entrances and stairwells and window and door perimeters on blocks, and the usual reasons a site gets in touch are communal area joints that look neglected and failed external movement joints. One point of contact handles commercial sealant work in Claygate Cross from the first photographs to the final walk-round, whether it’s one building or several.
For buildings around smaller places like Claygate Cross, we group work so one trip covers it. Send photographs of the frames and joints and we will give a fixed quote.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Keeping the joints sound
Regular inspection catches problems early. In particular:
- Have the asbestos survey to hand for older buildings
- Make it easy for occupiers to report draughts
- Keep a record of when each building was resealed
- Plan resealing building by building rather than complaint by complaint
Encourage occupiers to report water or draughts at frames. A quick report keeps a small repair small.
Joints on a building age together, so it pays to look at the whole elevation. A planned reseal saves repeated visits.
Mastic sealing around Claygate Cross: what changes locally
At about 23 miles from central London, Claygate Cross is within reach of the capital. Managed blocks of flats are a big part of commuter-belt property; their frame mastic often ages block-wide. Claygate Cross sits in one of the drier corners of the country, the South East. Even so, frame mastic only goes on in dry, workable conditions, while the elevations that take the most sun tend to show hardened mastic first.
Schools and community buildings such as Borough Green Primary School need frame and external mastic kept sound like any building. Landlords with units on estates such as Bourne Enterprise Centre, 1.3 miles to the north of Claygate Cross, can bring frame, door and external mastic across several units into one programme.

Common questions from Claygate Cross clients
Do you cover business parks and estates near Claygate Cross, such as Bourne Enterprise Centre?
Yes. We cover Claygate Cross and the area around it, including industrial estates, business parks and retail parks such as Bourne Enterprise Centre. Photos and a short description are enough for a first look.
Will you take on a block within reach of Borough Green & Wrotham station?
Yes, we work for agents, landlords and housing associations with blocks of every size. Photos of each elevation help us quote accurately.
Is asbestos a concern with old mastic?
In older buildings, old mastic can contain asbestos. We ask for the asbestos register or survey before work starts and suspect material is tested first.
How long do sealant joints last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
Can you reseal a whole block or estate?
We can. We survey and price each building, then work through them in order starting wherever is most urgent.
How do you handle work on occupied blocks?
Residents and tenants carry on as normal. If any flats or units need access, we will tell you in advance so it can be arranged.
Who decides which product is used?
The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Common problems we fix in Claygate Cross
UV and rain age external sealant. It stiffens, stops stretching and cracks, especially on south and west faces.
Most enquiries start with one or more of the following:
- No planned programme for sealant
- Patchy repairs in mismatched sealant
- Leaks at window and door perimeters
- Open joints in brickwork or panels
With historic buildings such as Old Soar Manor (to the south-east of Claygate Cross) in the wider area, owners of older properties around Claygate Cross should expect mastic to need a product that suits old masonry.

Why it’s worth doing now in Claygate Cross
Mixed repairs by different contractors leave a patchwork of products and colours. Resealing a whole building gives a consistent finish. For buildings around smaller places like Claygate Cross, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.
