Do you need mastic sealing in St George's Hill?
Sunlight and weather break mastic down over time. The surface chalks, the body stiffens and cracks appear, especially on south and west faces.
These are often picked up first by site or facilities staff:
- Water getting in round frames after rain
- No planned programme for sealant
- Damaged joints in communal entrances and corridors
- Movement joints with sealant missing
With historic buildings such as Byfleet Manor (to the south of St George's Hill) in the wider area, owners of older properties around St George's Hill should expect mastic to need a product that suits old masonry.

Site teams most often ask us about the same joint failures repeated across a portfolio and a mix of products and colours from past repairs, across communal entrances and stairwells, balcony and threshold joints and communal kitchens and washrooms. Most enquiries from St George's Hill start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

Why it’s worth doing now in St George's Hill
Resealing ahead of leaks keeps it to a maintenance task. Once water has tracked in, the repair list grows and occupiers notice. Small buildings around St George's Hill suffer from failed joints as much as large ones. Catching it early means a reseal rather than repairs.
The product called for affects the cost, and so does the preparation. Access, phasing and site requirements come into it too.

Your questions answered
We manage a building near Weybridge station. Can you help?
Yes. Blocks of any size are within what we do. Give us the building’s details and say how residents are notified, and we’ll quote and plan to suit.
Is a smaller place like St George's Hill outside your area?
No. Small places get the same service as large ones. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.
Does weather matter for sealant work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
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.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it.
Is it fine to apply new sealant on top of old?
No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Will residents or tenants be disturbed?
Residents and tenants carry on as normal. If any flats or units need access, we’ll tell you in advance so you can arrange it with occupiers.
Commercial clients in St George's Hill
Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.
Our process
Working in a building that stays open takes some planning. We sign and contain the area we are in, keep walkways clear and move on in phases so staff and visitors can carry on around us. Several jobs near St George's Hill can be grouped on one trip. Mention the building’s opening times and we will work within them.
- First comes a look at the joints and, for older buildings, the asbestos records.
- A fixed quote covers the joints, products and order of work.
- Failed mastic is removed completely.
- The joints are prepared and resealed with the right product.
- We finish each building before moving to the next.
Getting the site ready
- Send your site hours and access windows
- Explain the parking and delivery arrangements
- Move anything stored against the joints
Getting a fixed quote
Let us know the site, the scope and your timescale, and a fixed quote will follow. The easiest way is to call 01277 525 020 or send details through our quote form.

Maintenance after handover
After handover, a little attention goes a long way:
- Prioritise elevations facing the weather
- Group repairs into a planned programme
- Protect low-level joints in entrances
- Log resealing dates block by block
Keep bins, bikes and deliveries away from low-level joints where you can. Damage at low level is the most common reason communal joints fail early.
One failed perimeter normally means others on the same building are close so a single failure is a sign to check the rest. Doing them together saves going back again and again.
When it isn’t the sealant
Honesty saves time and money. New sealant won’t cure:
- Leaks through the frame itself rather than the perimeter
- Materials that need asbestos testing before work
- Masonry that has broken away beside the joint
Not sure which it is? You can give us a call on 01277 525 020 or email drawings and photos and we’ll tell you honestly before you book.

Blocks and managed buildings in St George's Hill
St George's Hill sits in one of the drier corners of the country, the South East. Outside mastic still needs a dry joint and the right temperature, while the elevations that take the most sun tend to show hardened mastic first. Three care or nursing homes sit less than 2 miles from St George's Hill. Care home owners need frame and external mastic kept sound without unsettling residents.
Landlords with units on estates such as Wintersells Business Park, 1.6 miles to the south-west of St George's Hill, can bring frame, door and external mastic across several units into one programme. Blocks of flats and mixed-use buildings often cluster around stations such as Weybridge station, 0.5 miles west of St George's Hill, and their window and balcony mastic tends to age at the same rate across a building.
