How we handle mastic sealing in Chaddleworth
Across Chaddleworth and the rest of West Berkshire, we work the same way: send details, get a fixed quote, we seal, and the work is guaranteed. A list of buildings, a few photos and approximate joint numbers are enough for a quick quote or we can visit. If you’re dealing with repeated reactive repairs to the same buildings and damaged joints in communal entrances and corridors, we can put it right. A specialist sealant contractor works differently from a general builder: in Chaddleworth, that means joint design, primers and backing rod as standard.
Around smaller places like Chaddleworth, 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.
Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Frames, entrances and external joints in Chaddleworth
At about 56 miles from central London, Chaddleworth is within reach of the capital. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres. Rainfall across the South East, Chaddleworth included, is lower than in many 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.
Schools and community buildings such as Chaddleworth St Andrew's C.E. Primary School need frame and external mastic kept sound like any building. Churches, halls and community buildings such as Church of St Andrew are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.

When something else is needed
Sealant solves a lot, but not everything, and we are upfront when that’s the case. It won’t fix:
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Asbestos-containing sealant, which we don’t remove
- Misted or failed double-glazed units
Not sure which it is? You can phone 01277 525 020 or email a schedule or drawings and we will tell you honestly.
Joints and surfaces we work on
- External wall and movement joints
- Communal entrances and stairwells
- Balcony and threshold joints
- Window and door perimeters on blocks
- Communal kitchens and washrooms
- Shopfronts below residential blocks
Surface by surface
External movement joints
Movement joints are cleaned out, backed with rod and resealed with a sealant of the right movement class.
Commercial and mixed-use buildings
Commercial occupiers typically stay open during the work, so we plan around them.
How a job runs
Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. Smaller jobs around Chaddleworth can be grouped with others nearby. A fixed quote is given before anything starts.
- Each block or building is walked and the failed joints recorded with the likely cause.
- A fixed quote follows, split by block or building if that suits you.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- 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.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
Before we start on site
- Let us know about inductions and permits
- Agree which areas must stay open
- Move anything stored against the joints

Owners, agents and contractors
CHAS accredited and a Constructionline member, we make supplier vetting simple. We’re fully insured, and our insurance certificate can go with the quote.
We work for building owners and managing agents on everything from one building to a spread of sites around Chaddleworth. One quote can cover more than one site, so there’s one set of paperwork to deal with.
After the work
For the best life from the joints:
- Keep a record of when each building was resealed
- Keep bins and bikes away from communal door frames
- Share the asbestos register when you send details
- Group repairs into a planned programme
Encourage occupiers to report water or draughts at frames. A quick report keeps a small repair small.
Left open, joint edges in render, brick or frames can deteriorate. Then the edges may need repairing first.
Questions about Chaddleworth
Is Chaddleworth too far out for you?
No. Small places get the same service as large ones. We work across Greater London and the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Will you price a mastic programme across our Chaddleworth portfolio?
Yes. Portfolio-wide programmes are a regular request. Send the addresses and photographs and we will give a fixed quote.
How do you choose the sealant?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Can you seal joints high up on a block?
Every block is different. We agree access with you at quote stage so the fixed quote reflects it.
What if the old mastic contains asbestos?
In older buildings, old mastic can contain asbestos. We ask for the asbestos register or survey before work starts, and if it’s suspected, work stops until it’s tested.
Do you work for managing agents and housing associations?
We do. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords, and we quote building by building or as a programme.
How soon can the area be used again?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.

Why deal with it now?
Draughts round window perimeters cost occupiers comfort and the windows typically get the blame. Resealing the perimeters is often the simpler fix when the frames themselves are sound. Older rural buildings around Chaddleworth move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
