Different surfaces, different methods
Window and door perimeters on blocks

Communal areas
Entrance doors, screens and corridor junctions in communal areas all have sealant joints. Fresh joints make shared areas look looked after.
How we handle mastic sealing in Marshborough
Most buildings come with mastic joints nobody has looked at since handover and it slowly wears out: window perimeters, door frames, external joints and communal junctions all rely on it. When it hardens, splits or pulls away, water and draughts follow along with complaints. The enquiries we see most involve estate-wide sealant that is simply worn out and leaks at window and door perimeters, across communal entrances and stairwells, communal kitchens and washrooms and window and door perimeters on blocks. For commercial sealant work in Marshborough, you deal with one contact from quote to sign-off, whether it’s one building or several.
Owners and agents with buildings around smaller places such as Marshborough tend to manage small terraces of association properties, converted barns and commercial units. Frame and wall-joint mastic on all of them ages and hardens.
Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Common questions from Marshborough clients
Is Marshborough off your patch?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
Can you work at a site such as Birnham Farm Business Centre, by Marshborough?
Yes. We cover Marshborough and the area around it, including industrial estates, business parks and retail parks such as Birnham Farm Business Centre. Send details of the unit and the work through our quote form for a quick quote.
Will residents or tenants be disturbed?
Residents and tenants carry on as normal. If any flats or units need access, we’ll tell you in advance so you can arrange it with occupiers.
When can the area be used after sealing?
We’ll confirm how long the chosen product needs to cure.
Can you seal joints high up on a block?
It depends on the building. How upper joints are reached is agreed before work is booked so there are no surprises.
Can you send RAMS and CSCS details before starting?
Our credentials include CHAS, Constructionline and public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
Will you come and look before quoting?
That depends on the size and complexity of the job. Simple work can often be priced from photos, and bigger or more complex jobs normally get a visit.

What we can’t put right
A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is any of the following:
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Cracked or crumbling render, brick or stone at the joint edges (we will tell you if so)
- Misted or failed double-glazed units
Not sure which it is? You can call 01277 525 020 or send photos by email and we’ll tell you honestly before you book.

What happens if it’s left?
Mixed repairs by different contractors leave a patchwork of products and colours. A block-wide reseal gives one product, one colour and one guarantee. Converted and older buildings near places like Marshborough tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
A quote for mastic joints depends on how many there are, their condition and the access, plus any specification you are working to. Ask us for a fixed quote.
