How we handle mastic sealing in East Burnham
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. Entrances and stairwells are kept in use throughout. We work on communal kitchens and washrooms, balcony and threshold joints and communal entrances and stairwells, and what we’re called in for most is the same joint failures repeated across a portfolio and cracked, hardened mastic round windows on a block. A single leaking joint is often how a building in East Burnham first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Owners and agents with buildings around smaller places such as East Burnham tend to manage small terraces of association properties, converted barns and commercial units. Mastic around frames and on external joints wears out in time, whatever the building.
Work we carry out in Buckinghamshire comes with a 12-month guarantee. Should something we installed fail, phone 01277 525 020 or use the quote form and we will come back to it.

Quoting for work in East Burnham
The price varies from site to site. Expect it to depend on:
- Phasing around occupants
- How accessible the joints are
- Site requirements such as inductions and permits
- How much there is to seal
We don’t publish prices, since every building and every scope is different. Call for a quote and we’ll price your job on its own details.
Sending details for a quote
A good diagnosis starts with the right details. Let us know:
- Where the site is, with the postcode
- Whether the building will be occupied during the work
- Access details, including height
- Any specification or named product
Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we will arrange one.

When it isn’t the sealant
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:
- Substrate edges that need repairing first
- Leaks through the frame itself rather than the perimeter
- Materials that need asbestos testing before work
If you’re not sure, just give us a call on 01277 525 020 or email the details over and we will give you a straight answer before you book.

Different surfaces, different methods
Tenement and older buildings
Traditional buildings have joints that need a careful approach. We look at the substrate before choosing a sealant.
Estate-wide resealing programmes
An estate of similar buildings suits a rolling programme. We quote building by building and work through them in turn.
Mastic sealing around East Burnham: how the place shapes the job
Rainfall across the South East, East Burnham included, is lower than in many parts of the UK. 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. Central London is about 23 miles from East Burnham. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres.
If you own or manage units on a site such as Bath Road Shopping Park (1.9 miles south of East Burnham), failed mastic on frames, door surrounds and external joints can be dealt with unit by unit. Older buildings near East Burnham, from historic houses such as Cliveden, 2.8 miles to the west of East Burnham, to more modest stock, need compatible products when frames are resealed.

Questions we are asked in East Burnham
Is East Burnham off your patch?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
Do you work for managing agents with blocks near Burnham station?
Yes, and several blocks can go on one quote. Send the address, photos of the elevations and your access arrangements, and we will give a fixed quote.
Can you plan resealing across several buildings?
We can. We survey and price each building, then work through them in order starting wherever is most urgent.
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
Do you supply RAMS and insurance details?
Our credentials include CHAS, Constructionline and public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
How do you choose the sealant?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Common problems we fix in East Burnham
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.
Typical triggers for a call:
- Leaks at window and door perimeters
- Draught complaints from residents or tenants
- Estate-wide sealant that is simply worn out
- Patchy repairs in mismatched sealant
Schools and community buildings such as Caldicott School need frame and external mastic kept sound like any building.
Questions to ask before you book
- The terms of the workmanship guarantee
- Their plan for phasing and protecting the area
- Their pre-qualification and accreditations
- Do they follow the manufacturer’s priming guidance?
