Work for main contractors and building owners
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.
If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
How we handle mastic sealing in Winkfield Street
Across Winkfield Street and the rest of Bracknell Forest, we work the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Addresses, photos of typical joints and a rough idea of quantities let us give a quick quote or we can visit. We work on communal entrances and stairwells, shopfronts below residential blocks and communal kitchens and washrooms, and the failures we are asked to look at most are worn sealant at communal door frames and damp patches beside frames. One point of contact handles commercial sealant work in Winkfield Street from the first photographs to the final walk-round, for single jobs and planned programmes alike.
In and around smaller places like Winkfield Street, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Mastic around frames and on external joints wears out in time, whatever the building.
Our workmanship is guaranteed for 12 months, in Winkfield Street as everywhere else we work. If our installation lets you down in that time, we return and fix it.

What happens if it’s left?
Draughts round window perimeters cost occupiers comfort, and they often blame the windows. Resealing the perimeters is often the simpler fix when the frames themselves are sound. Older rural buildings around Winkfield Street move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a fixed quote once you have the details.

What else we do in Winkfield Street
Our process
In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then reopened once the sealant allows before the next one starts. Smaller jobs around Winkfield Street can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.
- We inspect the joints, building by building, and record what has failed and why.
- 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.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
What we need from you
- Share the asbestos register for older buildings
- Have the specification and drawings to hand
- Share your working hours and any access restrictions
Getting a fixed quote
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we will arrange a site visit if anything is unclear.
Related advice
Block-wide mastic in Winkfield Street
Winkfield Street is in the South East, one of the UK’s drier regions. External mastic still waits for dry faces and the right temperature, and the sunniest, most exposed sides of a building typically need attention first. Winkfield Street lies roughly 27 miles out from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres.
Blocks of flats and mixed-use buildings often cluster around stations such as Martins Heron station (2.8 miles south of Winkfield Street) and their window and balcony mastic tends to age at the same rate across a building. If you manage student housing near a university such as Imperial College Silwood Park Campus, which lies south-east of Winkfield Street, the summer turnaround is the time for mastic. Older buildings near Winkfield Street, from historic houses such as St Leonard's Hill, 2.8 miles to the north-east of Winkfield Street, to more modest stock, need compatible products when frames are resealed.

Questions about Winkfield Street
Is Winkfield Street too small for you to travel to?
Not at all. Winkfield Street is within our area. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Can one quote cover a number of our buildings near Winkfield Street?
Yes, we quote for single buildings and for programmes across several blocks. Send the addresses and photographs and we will give a fixed quote.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
Is asbestos a concern with old mastic?
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.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
Is mastic sealing guaranteed?
A 12-month guarantee covers our work. It covers our workmanship, not later building movement, damage or frame failures.
Does the weather affect the work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
Keeping the joints sound
Once the work is signed off, a little attention goes a long way:
- Look at the sunniest and most exposed elevations first
- Mention RAMS, insurance or CSCS requirements up front
- Check the asbestos register before any old mastic is disturbed
- Avoid piecemeal callouts where you can
Keep records of when each building was resealed. That makes future programmes easier to plan and shows what was done.
Budgets are easier to plan when sealant is part of planned maintenance. We can quote buildings in priority order so spending is spread.
Doing it in-house
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Redoing a failed joint usually costs more than getting it right at the outset, 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.
When it isn’t the sealant
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Materials that need asbestos testing before work
- Misted or failed double-glazed units
- Roof leaks, gutters or failed flashings that aren’t sealant joints
Not sure which it is? You can speak to us on 01277 525 020 or email the details over and we will tell you honestly.
