Advice
Mastic sealing in Sherfield English, done properly
Treatment starts with a proper look: what has failed, what caused it and whether new sealant will actually solve it. Failed mastic is stripped, the faces taken back to sound material, primed where the manufacturer specifies and resealed and backing rod used wherever a joint is deep. Site teams most often ask us about damp patches beside frames and failed external movement joints, across balcony and threshold joints, communal entrances and stairwells and external wall and movement joints. Most enquiries from Sherfield English start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
For buildings around smaller places like Sherfield English, we group work so one trip covers it. Send photos of the frames and joints and we’ll give a fixed quote.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Looking after the joints
Problems stay small when the joints are checked regularly. Specifically:
- Ask residents or tenants to report leaks and draughts early
- Avoid piecemeal callouts where you can
- Mention RAMS, insurance or CSCS requirements up front
- Look at the sunniest and most exposed elevations first
Encourage occupiers to report water or draughts at frames. A quick report keeps a small repair small.
Planned resealing is easier to budget than emergency repairs. We can quote buildings in priority order so spending is spread.

Leave it or put it right?
Adding sealant to cyclical maintenance is an easy win. Waiting until leaks appear means working under pressure with less control over timing. For buildings around smaller places like Sherfield English, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

Common problems we fix in Sherfield English
Occasionally the substrate fails, not the sealant for example where render or brick edges crumble. If the edges are unsound, we say so before quoting the sealing.
If one of these sounds familiar, it’s time for a closer look:
- Draughts at frames across a block
- A mix of products and colours from past repairs
- Brittle perimeter mastic across a building
- Repeated reactive repairs to the same buildings
If you own or manage units on a site such as Gardeners Business Park, 1.2 miles to the south of Sherfield English, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.
What to look for in a quote
- The terms of the workmanship guarantee
- What level of public liability insurance do they hold?
- Whether old or failed sealant will be cut out, not overlaid
- Which product they’ll use, and why it suits the joint
Should maintenance staff do it?
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

How do you reach windows on upper floors?
Access is discussed and agreed before the quote is fixed. Tell us the number of storeys and whether scaffold or other access is planned and we’ll confirm the approach in the quote.
Will you just go over the old sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
How do you choose the sealant?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Mastic sealing around Sherfield English: how the place shapes the job
The South East is one of the drier parts of the UK. External mastic still waits for dry faces and the right temperature, while the elevations that take the most sun tend to show hardened mastic first.
With historic buildings such as Landford Manor (to the south-west of Sherfield English) in the wider area, owners of older properties around Sherfield English should expect mastic to need a product that suits old masonry. Churches, halls and community buildings such as Church of St Leonard are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.
