Mastic sealing near Boyn Hill
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Honest limits
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Misted or failed double-glazed units
- Substrate edges that need repairing first
- Roof leaks, gutters or failed flashings that aren’t sealant joints
Not sure which it is? You can give us a call on 01277 525 020 or email a schedule or drawings and we’ll tell you honestly.
Surfaces we seal
- Balcony and threshold joints
- Communal kitchens and washrooms
- Communal entrances and stairwells
- Window and door perimeters on blocks
- External wall and movement joints
- Shopfronts below residential blocks
Mastic sealing in Boyn Hill, done properly
Treatment starts with a proper look: what has failed, what caused it and whether new sealant will actually solve it. Failed mastic is stripped, the faces taken back to sound material, primed where the manufacturer specifies and resealed and backing rod used wherever a joint is deep. We work on external wall and movement joints, communal entrances and stairwells and window and door perimeters on blocks, and the failures we are asked to look at most are draughts at frames across a block and movement joints with sealant missing. A single leaking joint is often how a building in Boyn Hill first comes to us: we look at the rest while we are there and tell you what we find.
For landlords and associations with stock in and around Boyn Hill, grouping buildings into one visit saves travel. One quote can cover a whole list of addresses.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Our process
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. For a site in Boyn Hill, we plan so the whole job is done in one go where possible. Clear photos and measurements help us bring the right products.
- We inspect each building and record the joints that have failed.
- You get a fixed quote, per block or for the whole programme.
- Dates and areas are agreed so occupiers can be told.
- Old mastic is removed and the joint faces prepared.
- New sealant goes in with backing rod and primer where needed.
- We check the finished work and confirm the guarantee.
Before we start on site
- Share the asbestos register for older buildings
- Let building users know which areas are affected
- Point out parking and an unloading spot

Leave it or put it right?
Reacting to every complaint means sending someone out block by block. A planned programme treats each building once and is simpler to manage and budget. Sealant hardens, cracks and loses grip with age, UV and movement. Replacing it before it fails keeps water out.
What a job costs comes down to how many linear metres there are, what has to come out first and how the joints are reached. Call for a quote when you’re ready.

When to call us in Boyn Hill
In communal areas, joints take knocks from bins, bikes, buggies and deliveries, with joints near the floor and around doors suffering most. Cleaning products add to the wear.
These are often picked up first by site or facilities staff:
- Patchy repairs in mismatched sealant
- Draughts at frames across a block
- Communal area joints that look neglected
- Window mastic that has split and shrunk
If you look after a block within reach of Maidenhead station, 1 mile to the north-east of Boyn Hill, frame and balcony mastic can be renewed on one programme.

Mastic sealing around Boyn Hill: what changes locally
The 2 miles around Boyn Hill include two care or nursing homes. Frame mastic on care buildings is best renewed elevation by elevation, with the manager deciding timings. Boyn Hill 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 usually where frame mastic ages first.

Schools and community buildings such as Larchfield Primary and Nursery School need frame and external mastic kept sound like any building.

Common questions from Boyn Hill clients
Will you take on a block within reach of Maidenhead station?

Yes. Estates, retail parks and business parks around Boyn Hill, Vanwall Business Park among them, are all within reach. Photos and a short description are enough for a first look.
Will residents or tenants be disturbed?
Occupiers stay in the building throughout. We flag any areas that need internal access well before the dates so it can be arranged.
How long does a job like this take?
That varies with the scale of the job, but the work usually takes one or more days per building, depending on the joint lengths and the access. For bigger or phased jobs, we will set out a timescale with the quote.
Can you send RAMS and CSCS details before starting?
We are CHAS accredited, a Constructionline member and carry public liability insurance. For specific documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.
Who decides which product is used?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
After the work
To get the most from the new sealant:
- Protect low-level joints in entrances
- Log resealing dates block by block
- Start inspections with the most exposed faces
- Group repairs into a planned programme
Add mastic joints to your cyclical inspections. Check for splits, open joints, brittle mastic and lifting edges and record where they are.
Failed mastic often goes unnoticed until heavy rain finds it. Acting at the first signs keeps it a straightforward reseal and the complaints that come with it.
