How we handle mastic sealing in Charvil
Managing agents and housing associations typically need paperwork before anyone starts.

We’re a Constructionline member and CHAS accredited, and we carry public liability insurance. Site teams most often ask us about draught complaints from residents or tenants and window mastic that has split and shrunk, across balcony and threshold joints, shopfronts below residential blocks and communal entrances and stairwells. Searching for sealant specialists in Charvil? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
Older buildings and conversions around places like Charvil mix old masonry with newer frames. Perimeter joints need a sealant that suits both frame and masonry.

Questions about Charvil
Is Charvil off your patch?
No. Small places get the same service as large ones. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.
Will you take on a block within reach of Twyford station?
Yes. Blocks of any size are within what we do. Send the address, photographs of the elevations and your access arrangements, and we’ll give a fixed quote.
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 tell you how we’d approach it.
Can weather delay the job?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
How long will the new sealant last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
How long does a job like this take?
The duration is planned around your programme and the access we’re given. You’ll have an expected duration with the quote.
Who decides which product is used?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
How the job changes by surface
Tenement and older buildings
Stone needs a neutral-cure product, so we pick a grade that won’t mark it.
Window and door perimeters on blocks
On most blocks, the frame-to-wall joint is where failure shows first. We remove the failed mastic, prepare the faces, add backing rod if the joint is deep and reseal.
Diagnose, treat, sign off
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself normally takes a few days for most blocks, with larger programmes scheduled building by building, and we clear our waste as we work. Several jobs near Charvil can be grouped on one trip. Mention the building’s opening times and we’ll work within them.
- A building-by-building inspection lists the failed joints.
- You get a fixed quote, per block or for the whole programme.
- Dates and areas are agreed so occupiers can be told.

Keeping the joints sound
After handover, these steps help:
- Share the asbestos register when you send details
- Keep bins and bikes away from communal door frames
- Prioritise elevations facing the weather
- Log resealing dates block by block
If a joint we sealed fails within 12 months, tell us and we will look at it. Beyond that, routine checks spot the next round of repairs.
The longer failed joints are left, the more likely the substrate edges break up. Then the edges may need repairing first.
Mastic sealing in Charvil: the local picture
At about 34 miles from central London, Charvil 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. Charvil is in the South East, one of the UK’s drier regions. 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.
Blocks of flats and mixed-use buildings often cluster around stations such as Twyford station (0.9 miles east of Charvil) and their window and balcony mastic tends to age at the same rate across a building. Student accommodation around universities such as University of Reading, 1.9 miles to the north-west of Charvil, is typically managed block by block, which suits a planned mastic programme.
Charvil is about 2 miles north of Woodley, in Wokingham. Any commercial site in Charvil is covered. 42 places across Wokingham fall within our area, Charvil among them.
Work on mastic joints is covered throughout RG10, for business premises of every kind. Streets here include Old Bath Road, Wenlock Edge and Pipistrelle Way. We also cover Twyford (1 mile east), Ruscombe (1 mile east), Whistley Green (1 mile south-east), Woodley (2 miles south) and Shiplake (2 miles north) for mastic joints. Further afield, our area takes in Wokingham (5 miles south), Earley (4 miles south-west), Crowthorne (8 miles south-east), Lower Earley (4 miles south-west), Winnersh (3 miles south) and Shinfield (6 miles south-west).
