Need mastic sealing in Bisley?
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
How the quote is worked out
To price the job, we consider:
- Induction, permit and paperwork requirements
- Quantities, in metres or numbers
- Whether old sealant has to be cut out first
- The product specified
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we will explain how it’s made up.
What we need to price the job
The more we know, the firmer the quote. Helpful details to send:
- Specification clauses that apply
- Approximate linear metres or a joint schedule
- Clear photos of the problem areas
- Asbestos survey details if the building is older
Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. The easiest way is to call the office on 01277 525 020 or send details through our quote form.
How we handle mastic sealing in Bisley
Different joints need different sealants. Window perimeters and external joints often take a low-modulus neutral-cure silicone, and MS polymer sealants stick well to many substrates and often take paint, and colours are confirmed for whichever product is used. If you have water getting in round frames after rain and communal area joints that look neglected, we can help. Whoever orders the work in Bisley, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
For landlords and associations with stock in and around Bisley, grouping buildings into one visit saves travel. Send the addresses and photographs and we’ll quote for all of them together.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Other services in Bisley
Building owners, agents and FMs in Bisley
Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
Our process
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. If neighbouring businesses or buildings around Bisley need work too, visits can be combined. Mention the building’s opening times and we will work within them.
- Each block or building is walked and the failed joints recorded with the likely cause.
- We send a fixed quote that sets out the joints, the products and the programme.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- Failed mastic is removed and the faces taken back to sound, dry material.
- 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.
Preparing the site
- Tell us what induction or permit system the site runs
- Point out any areas we must not close
- Confirm the product named in the specification
Request a quote
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.
Advice
Surface by surface
Planned maintenance
How long mastic lasts depends on exposure, movement and the product used. Inspecting joints regularly keeps programmes on track.
Window and door perimeters on blocks
Frames vary from uPVC to aluminium and timber, and the product is matched to the frame material and the masonry. Colours are confirmed for the product used.
What sealant work can’t fix
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Leaks from above rather than through a joint
- Substrate edges that need repairing first
- Asbestos-containing sealant, which we don’t remove
If you are not sure, just call the office on 01277 525 020 or email the details over and we’ll give you a straight answer before you book.
What we seal
- Communal entrances and stairwells
- Window and door perimeters on blocks
- External wall and movement joints
- Balcony and threshold joints
- Shopfronts below residential blocks
- Communal kitchens and washrooms
When to call us in Bisley
We often find joints filled solid with no backing rod, so the mastic is glued to the joint bottom too. That three-sided adhesion stops it stretching and it tears.
These are often picked up first by site or facilities staff:
- Open joints in brickwork or panels
- Brittle perimeter mastic across a building
- No planned programme for sealant
- Damaged joints in communal entrances and corridors
Site managers at schools like Bisley CofE Primary School can fit frame mastic into the summer works.

Mastic sealing around Bisley: points for this area
The South East is one of the drier parts of the UK. Outside work still depends on dry joints, while the elevations that take the most sun tend to show hardened mastic first. Central London is about 26 miles from Bisley. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres, and window and balcony mastic on them tends to age at the same rate.
Property owners at sites such as Goldsworth Park Trading Estate (to the east of Bisley) can have mastic renewed between lettings. If you look after a block within reach of Brookwood station (1.6 miles south of Bisley), frame and balcony mastic can be renewed on one programme.

Your questions answered
Do you work for managing agents with blocks near Brookwood station?
Yes, and several blocks can go on one quote. We work to your notice and access arrangements.
Is Bisley off your patch?
Not at all. Bisley is within our area. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
Do you check for asbestos in old sealant?
We don’t remove asbestos-containing materials. If old sealant is suspected, work stops until it’s tested in line with the dutyholder’s asbestos management.
Do you work for managing agents and housing associations?
Yes, block and estate work is a core part of what we do. We work through buildings in a planned order so you can plan around it.
When is resealing likely to be due?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
How do you choose the sealant?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
How do you reach windows on upper floors?
Every block is different. We agree access with you at quote stage so there are no surprises.
