About our mastic sealing in Compton
Treatment starts with a proper look: which joints have failed, why, and whether sealant is the right answer. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in and backing rod used wherever a joint is deep. We work on communal kitchens and washrooms, shopfronts below residential blocks and window and door perimeters on blocks, and what we’re called in for most is movement joints with sealant missing and damaged joints in communal entrances and corridors. Most enquiries from Compton start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
In and around smaller places like Compton, 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.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

When something else is needed
Before quoting, we check that sealant is the right answer. It won’t put right:
- Misted or failed double-glazed units
- Materials that need asbestos testing before work
- Leaks through the frame itself rather than the perimeter
If in doubt, call 01277 525 020 or email us and we will say what we think.
Joints and surfaces we work on
- Communal entrances and stairwells
- Balcony and threshold joints

- Communal kitchens and washrooms
- External wall and movement joints
- Shopfronts below residential blocks

For owners and agents in Compton
Central London is about 63 miles from Compton. Managed blocks of flats are a big part of commuter-belt property. The South East is one of the drier parts of the UK. Outside work still depends on dry joints, and elevations facing the sun and the prevailing weather are typically where frame mastic ages first.
Landlords with units on estates such as Hazeley Enterprise Park, 1.4 miles east of Compton, can bring frame, door and external mastic across several units into one programme. Buildings close to stations like Shawford station (0.5 miles east of Compton) are often flats over shops, with frame mastic to keep sound.

When to call us in Compton
Occasionally the substrate fails, not the sealant for example where render or brick edges crumble. We will tell you if the joint edges need repairing before resealing.
Clients typically get in touch after noticing one or more of the following:
- Cracked, hardened mastic round windows on a block
- Complaints coming in block by block
- Worn sealant at communal door frames
- Old repairs sealed over failed mastic
Owners of student blocks near University of Winchester (to the north of Compton) can schedule frame and external mastic for the summer vacation.

- Will CSCS-carded applicators be on site?
- Whether primer will be used where the manufacturer specifies it
- How the existing material will be dealt with
Work for main contractors and building owners
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, and our applicators hold CSCS cards.
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Compton can sit alongside others in a wider programme across Hampshire.
How the job changes by surface
Communal areas
Communal entrances, stairwells and corridors have joints at door frames, screens, skirting and floor edges. Fresh joints make shared areas look looked after.
Tenement and older buildings
Some old mastics in pre-2000 buildings contain asbestos, so we check the asbestos register or survey first. If it’s suspected, work stops until it’s tested.

What affects the price in Compton
Your fixed quote is built from the real scope. It takes account of:
- Joint width, depth and condition
- Phasing around occupants
- Quantities, in metres or numbers
- How accessible the joints are
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
Sending details for a quote
However big the job, these details speed things up:
- Photos of the joints, close up and from further back
- What the building is and how it’s used
- How the joints are reached, and at what height
- Asbestos survey details if the building is older
A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or call the office on 01277 525 020 or send details through our quote form if you’d rather talk the job through.
