Signs you need mastic sealing in Upton
Topping up old mastic is a common shortcut. New silicone has nothing to grip on old silicone and the repair soon fails.
It’s worth sending us details if you spot any of the following:
- Failed external movement joints
- Water getting in round frames after rain
- The same joint failures repeated across a portfolio
- No planned programme for sealant
Landlords with units on estates such as Nursling Industrial Estate, 0.8 miles to the south-west of Upton, can bring frame, door and external mastic across several units into one programme.
Questions to ask before you book
- Will CSCS-carded applicators be on site?
- Are they CHAS accredited or on Constructionline?
- Their approach to joint depth and backing
- The terms of the workmanship guarantee
Mastic sealing in Upton, done properly
We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. A planned, building-by-building programme often works better than reacting to each complaint, with each block quoted and scheduled in turn. If you’re dealing with communal area joints that look neglected and open joints in brickwork or panels, we can put it right, whatever the surface. One point of contact handles commercial sealant work in Upton from the first photos to the final walk-round, for single jobs and planned programmes alike.
Owners and agents with buildings around smaller places such as Upton 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.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

The work itself normally takes a day or two for a single block, longer for an estate programme, and our waste is bagged and taken away as we go. For work around Upton, we aim to finish in one visit, so photos and measurements up front really help. That way the right products come on the day.
- We check the asbestos register for older buildings and look at the joints.
- The products and programme are set out in a fixed quote.

Advice
Surface by surface
Communal areas
Entrance doors, screens and corridor junctions in communal areas all have sealant joints. Tidy, sound joints keep them looking cared for.
Window and door perimeters on blocks
Window and door perimeters are where most mastic failure shows. Old perimeter mastic is removed, the joint prepared and new sealant tooled in.
Upton: questions and answers
We manage a building near Redbridge station. Can you help?
Yes, we work for agents, landlords and housing associations with blocks of every size. Give us the building’s details and say how residents are notified, and we’ll quote and plan to suit.
Can being near the sea in Upton affect the sealant we need?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
When can the area be used after sealing?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
Do you work for managing agents and housing associations?
Yes, that’s exactly who this service is for. Buildings are scheduled in turn so you can plan around it.
What paperwork can you provide?
We’re 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 will confirm with the quote.
How do you handle work on occupied blocks?
The work is planned around occupiers. Dates and areas are agreed with you so residents or tenants can be told, and entrances stay in use.
Is asbestos a concern with old mastic?
In older buildings, old mastic can contain asbestos. We check the asbestos register or survey before disturbing it and suspect material is tested first.
For owners and agents in Upton
Upton lies within about 3 miles of the sea. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints, and they deserve more regular inspection. The South East is one of the drier parts of the UK. External mastic still waits for dry faces and the right temperature, while the elevations that take the most sun tend to show hardened mastic first.
For agents with blocks near Redbridge station, 2.1 miles to the south of Upton, a block-wide mastic programme deals with frames, balconies and entrances in one go. Student accommodation around universities such as University of Southampton (3.4 miles south-east of Upton) is usually managed block by block, which suits a planned mastic programme.
Upton is about 2 miles north-west of Regents Park, in Hampshire. We cover commercial sites throughout Upton, for single jobs and planned programmes alike. Across Hampshire, 723 places are covered, including Upton.

We also cover Nursling (1 mile south), Rownhams (1 mile east), Ashfield (1 mile north-west), Toothill (1 mile north) and Hillyfields (1 mile south). A short drive away, we cover Winchester (10 miles north-east), Eastleigh (6 miles east), Fareham (14 miles south-east), Totton (3 miles south-west), Chandler's Ford (4 miles north-east) and Hedge End (8 miles east).

When something else is needed
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:
- Glazing that needs replacing
- Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
- Asbestos-containing sealant, which we don’t remove
If in doubt, call 01277 525 020 or email drawings and photos and we will say what we think before you book.
What we seal
- Balcony and threshold joints
- Window and door perimeters on blocks
- Communal kitchens and washrooms
- Communal entrances and stairwells
- Shopfronts below residential blocks
- External wall and movement joints
Doing it in-house
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
