Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
Our process
On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, with the work itself normally taking anything from a day to a few weeks, depending on the number of buildings and joints. If others near Leverton need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- First we look at the mastic on each building and note what needs replacing.
- We send a fixed quote that sets out the joints, the products and the programme.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- 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.
- Finished joints are looked over and the 12-month guarantee confirmed.
Preparing the site
- Have the specification and drawings to hand
- Warn occupants and staff about the work
- Point out any areas we must not close

Mastic sealing in Leverton
Treatment starts with a proper look: which joints have failed, why, and whether sealant is the right answer. 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. If you have no planned programme for sealant and the same joint failures repeated across a portfolio, we can put it right, whatever the surface. Searching for sealant specialists in Leverton?

Around smaller places like Leverton, older walls fitted with newer windows are a familiar sight. Perimeter mastic there has to grip an uneven face and suit the building’s character.

Common problems we fix in Leverton
Topping up old mastic is a common shortcut. New sealant won’t grip failed sealant and the repair soon fails.
Any of the following is a good reason to get the joints checked over:
- Worn sealant at communal door frames
- A mix of products and colours from past repairs
- Failed external movement joints
- Complaints coming in block by block
Trustees of buildings like Church of St Mary can bring frame and external mastic into a planned maintenance list.
What to look for in a quote
- Which product they’ll use, and why it suits the joint
- The terms of the workmanship guarantee
- Can the work be phased to keep areas open?
- How the joint faces will be prepared and primed
Frames, entrances and external joints in Leverton
The South East is one of the drier parts of the UK. Outside mastic still needs a dry joint and the right temperature, and the sunniest, most exposed sides of a building typically need attention first. Leverton lies roughly 62 miles out from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres.
With historic buildings such as Ramsbury Manor, 4.6 miles west of Leverton, in the wider area, owners of older properties around Leverton should expect mastic to need a product that suits old masonry. For owners of several units at places like Charnham Business Park, 0.7 miles south-east of Leverton, one programme can deal with frame and external mastic across the lot.
Leverton is about 9 miles west of Newbury, in West Berkshire. We cover Leverton and the rest of West Berkshire, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Across West Berkshire, 140 places are covered, including Leverton. There’s a separate page for Reading, about 24 miles away.

What’s near Leverton

Aftercare for building managers
After handover, a little attention goes a long way:
- Protect low-level joints in entrances
- Have the asbestos survey to hand for older buildings
- Look at the sunniest and most exposed elevations first
- Share your contractor requirements early
If paintable sealant was used, decoration can follow once it has cured. Non-paintable silicone shouldn’t be painted over.
Planned resealing is easier to budget than emergency repairs. A programme can start with the worst buildings so spending is spread.
What happens if it’s left?
Mixed repairs by different contractors leave a patchwork of products and colours. Resealing a whole building gives a consistent finish. One visit to deal with every failing joint makes more sense than several trips to a place like Leverton. Send photos of each area and we’ll quote for the lot.
We don’t publish prices, since every building and every scope is different. Call for a quote.
Why appoint us

What we can’t put right
Honesty saves time and money. Fresh joints won’t solve:
- Glazing that needs replacing
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Asbestos-containing sealant, which we don’t remove
Not sure which it is? You can phone 01277 525 020 or use the quote form and we’ll tell you honestly before you book.
Joints and surfaces we work on
- External wall and movement joints
- Communal kitchens and washrooms
- Window and door perimeters on blocks
- Shopfronts below residential blocks
- Balcony and threshold joints
- Communal entrances and stairwells
What the job involves on each surface
Planned maintenance
Mastic wears out like any building component; how fast comes down to movement, weather, UV and the product. Regular inspection is the best way to plan resealing.
Estate-wide resealing programmes
Consistent products and colours across an estate make future maintenance simpler.
