Mastic sealing near Cookham
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
How we handle mastic sealing in Cookham
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. We’ll confirm the colours available for the specified product. We work on shopfronts below residential blocks, window and door perimeters on blocks and balcony and threshold joints, and the failures we’re asked to look at most are damaged joints in communal entrances and corridors and complaints coming in block by block. Most enquiries from Cookham 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.
Older buildings and conversions around places like Cookham mix old masonry with newer frames. Perimeter joints need a sealant that suits both frame and masonry.
A 12-month guarantee applies to all our work in Windsor and Maidenhead. Should something we installed fail, call 01277 525 020 or email a schedule or drawings and we will come back to it.

Why deal with it now?
Open external joints let water into walls and around frames. Damp patches, stained plaster and decorating claims can follow and those cost far more to put right. In a smaller place such as Cookham, getting a contractor back for a second visit takes time, so we’d suggest renewing all the joints that are going, not just the worst.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

What the job involves on each surface
Tenement and older buildings
Older buildings, including Scotland’s sandstone tenements, have their own joint details. The material either side of the joint shapes the product choice.
Commercial and mixed-use buildings
Where retail and residential share a building, so phasing has to suit both. We plan around the site hours and access windows you give us.

Aftercare for building managers
Regular inspection catches problems early. In particular:
- Group repairs into a planned programme
- Reduce knocks to communal area joints
- List the paperwork your organisation requires when you send details
- Check sealant joints during planned building inspections
Ask residents or tenants to report draughts or leaks round windows early. A quick report keeps a small repair small.
Leaks at window perimeters spoil finishes and can affect frames. Resealing early keeps the job small.
From enquiry to sign-off
Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before we move to the next. For a site in Cookham, we plan so the whole job is done in one go where possible. Clear photographs and measurements help us bring the right products.
- First we look at the mastic on each building and note what needs replacing.
- You get a fixed quote, priced per building where that helps your budgeting.
- The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- We remove the old mastic completely and clean the joint faces back.
- Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
Before we start on site
- Clear stock, furniture or equipment away from the joints
- Tell us your opening times and when work is allowed
- For older buildings, check the asbestos register before work

When to bring in a specialist
Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
Block-wide mastic in Cookham
Cookham lies roughly 28 miles out from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres, and window and balcony mastic on them tends to age at the same rate. Cookham is in the South East, one of the UK’s drier regions. Outside mastic still needs a dry joint and the right temperature, and elevations facing the sun and the prevailing weather are normally where frame mastic ages first.
Buildings close to stations like Cookham station (under half a mile east of Cookham) are often flats over shops, with frame mastic to keep sound. Owners of student blocks near Buckinghamshire New University, 5 miles north of Cookham, can schedule frame and external mastic for the summer vacation. Property owners at sites such as Cliveden View Shopping Centre (to the south of Cookham) can have mastic renewed between lettings.

Your questions answered
Does your area include sites such as Cliveden View Shopping Centre, near Cookham?
Yes. We cover Cookham and the area around it, including industrial estates, business parks and retail parks such as Cliveden View Shopping Centre. To start, just call the office on 01277 525 020 or use the quote form with the unit, the joints involved and your access times.
Can you quote for a block close to Cookham station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. We work to your notice and access arrangements.
When is resealing likely to be due?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
How long does a typical visit take?
It depends on the scope, but the work usually takes a day or two for a single block, longer for an estate programme. For bigger or phased jobs, we will set out a timescale with the quote.
Do you seal on top of existing sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
What about access for upper-floor joints?
It depends on the building. How upper joints are reached is agreed before work is booked so the fixed quote reflects it.

Yes. We take on work across Cookham.
