Mastic sealing for Tongwell sites
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Diagnose, treat, sign off
Site rules come first: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you, and each area is checked before we leave it. If others near Tongwell need work, visits can be combined. You will have a fixed quote before work starts.
- 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.
Before we start on site
- Let us know about inductions and permits
- Send your site hours and access windows
- Agree which areas must stay open

Advice
Mastic sealing for commercial buildings in Tongwell
Blocks are lived in, so access and disruption have to be thought through. Dates, areas and the order of work are agreed with you in advance so you can let residents know what is happening. Communal entrances and stairs stay usable throughout. We work on balcony and threshold joints, communal kitchens and washrooms and window and door perimeters on blocks, and the failures we’re asked to look at most are window mastic that has split and shrunk and no planned programme for sealant. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Tongwell, that means joint design, primers and backing rod as standard.
In and around smaller places like Tongwell, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Frame and wall-joint mastic on all of them ages and hardens.
Work we carry out comes with a 12-month guarantee. If an installation problem shows up, give us a call on 01277 525 020 or email drawings and photos and we’ll arrange a return visit.

Cost factors for mastic joints
Quotes vary with the job. Expect it to depend on:
- Specialist products, such as fire-rated or hygienic sealants
- Joint width, depth and condition
- Whether the work must be split into stages
- Travel to remote or island sites
We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.
Details that help us quote
Diagnosis starts before we arrive. Tell us:
- Rough lengths or quantities, or drawings if you have them
- Whether the building will be occupied during the work
- Asbestos survey details if the building is older
- When you need the work done
Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.
Honest limits
Honesty saves time and money. New sealant won’t cure:
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Glazing that needs replacing
- Masonry that has broken away beside the joint
If in doubt, phone 01277 525 020 or send details through our quote form and we will say what we think before you book.

Why it’s worth doing now in Tongwell
Open external joints let water into walls and around frames. That can lead to damp, staining and damage to finishes and those cost far more to put right. For buildings around smaller places like Tongwell, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

What we are called out for in Tongwell
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 splits as the building moves.
What tends to prompt an enquiry:
- Water getting in round frames after rain
- Movement joints with sealant missing
- The same joint failures repeated across a portfolio
- Draught complaints from residents or tenants
Landlords with units on estates such as Blakelands Industrial Estate (0.8 miles north-west of Tongwell) can bring frame, door and external mastic across several units into one programme.
Questions to ask before you book
- How they’ll work around occupants
- Do they follow the manufacturer’s priming guidance?
- The named product and why it was chosen
- Who will actually carry out the work
Keeping the joints sound
For the best life from the joints:
- Make mastic part of routine maintenance checks
- Prioritise elevations facing the weather
- Group repairs into a planned programme
- Share your contractor requirements early
Where a paintable product was specified, it can be painted after curing. Silicone normally can’t be painted, so keep decorators off it.
Water getting in round frames can damage plaster, decoration and the frames themselves. Resealing early keeps the job small.
Blocks and managed buildings in Tongwell
At about 48 miles from central London, Tongwell is within reach of the capital. 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. Tongwell sits in one of the drier corners of the country, the South East. External mastic still waits for dry faces and the right temperature, while the elevations that take the most sun tend to show hardened mastic first.
Blocks of flats and mixed-use buildings often cluster around stations such as Milton Keynes Central station, 3 miles to the south-west of Tongwell, and their window and balcony mastic tends to age at the same rate across a building. Churches, halls and community buildings such as Church of St Mary Magdalene are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.
