Site staff or a sealant specialist?
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

What the job involves on each surface
External movement joints
The joint width has to suit the movement and the sealant’s capability, often around 2:1 width to depth, as the manufacturer advises.
Commercial and mixed-use buildings
Commercial buildings have mastic at shopfronts, entrances and external joints. A planned programme suits multi-building portfolios.

Do you work for managing agents with blocks near Andover station?
Yes, we work for agents, landlords and housing associations with blocks of every size. Photos of each elevation help us quote accurately.
Do you guarantee the mastic work?
There is a 12-month guarantee on our workmanship, backed by public liability insurance.
How do you handle work on occupied blocks?
We plan around people living or working in the building. Dates and areas are agreed with you so residents or tenants can be told and communal access is kept open.
Is Charlton in your area?
Yes. Charlton falls within our area, and you can ring 01277 525 020 or send photos by email to get started.
Do you check for asbestos in old sealant?
Asbestos removal isn’t part of our work. Anything suspect is tested before we carry on, and the duty to manage asbestos sits with the dutyholder.
How soon can the area be used again?
We will confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.
When something else is needed
Being straight saves everyone time. New sealant won’t cure:
- Misted or failed double-glazed units
- Substrate edges that need repairing first
- Water coming in from the roof or rainwater goods
If you’re not sure, just phone 01277 525 020 or use the quote form and we will give you a straight answer.

Block-wide mastic in Charlton
Central London is about 64 miles from Charlton. Managed blocks of flats are a big part of commuter-belt property, and window and balcony mastic on them tends to age at the same rate. Rainfall across the South East, Charlton included, is lower than in many parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, while the elevations that take the most sun tend to show hardened mastic first.
Site managers at schools like Harrow Way Community School can fit frame mastic into the summer works. Property owners at sites such as Mylen Road Business Park (0.8 miles south of Charlton) can have mastic renewed between lettings. Buildings close to stations like Andover station (to the south-east of Charlton) are often flats over shops, with frame mastic to keep sound.
Charlton is about 1 mile north-west of Andover, in Hampshire. Looking for mastic sealing in Charlton? We can help, as we do across Hampshire. Charlton is one of 723 places in Hampshire on our list. Sites around Southampton have their own page, about 22 miles away.

Local landmarks in Charlton

Other landmarks nearby include Andover War Memorial Hospital (0.5 miles south-east) and Andover Museum (1.3 miles south-east). Open spaces near Charlton include Anton Lakes and Mill Lake.
Why act early in Charlton
Leaving failed external joints lets water reach the structure behind. Damp patches, stained plaster and decorating claims can follow and those cost far more to put right. One visit to deal with every failing joint makes more sense than several trips to a place like Charlton. Photos of every joint help us quote for the whole job.
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.

After the work
Your facilities or cleaning team can help the joints last. Share these points with them:
- Group repairs into a planned programme
- Make mastic part of routine maintenance checks
- Make it easy for occupiers to report draughts
- List the paperwork your organisation requires when you send details
Our workmanship is covered for 12 months, so report any failure in that time. After that, regular inspection keeps the programme on track.
Water getting in round frames can damage plaster, decoration and the frames themselves. Early resealing is far simpler than repairs inside.
