Honest limits
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Substrate edges that need repairing first
- Failed window or door frames, which need a window contractor
- Materials that need asbestos testing before work

Mastic sealing for commercial buildings in Woodgreen
We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. Many prefer a planned programme to one-off visits, with each block quoted and scheduled in turn. We work on shopfronts below residential blocks, communal kitchens and washrooms and balcony and threshold joints, and the usual reasons a site gets in touch are brittle perimeter mastic across a building and leaks at window and door perimeters. A specialist sealant contractor works differently from a general builder: in Woodgreen, that means joint design, primers and backing rod as standard.
Rural conversions near places like Woodgreen often set modern frames into older stone, flint or brick. The mastic needs to suit an irregular masonry face and the look of the building.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Our process
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself normally takes a few days for most blocks, with larger programmes scheduled building by building, and our waste is bagged and taken away as we go. For work around Woodgreen, we aim to finish in one visit, so photos and measurements up front really help. That way the right products come on the day.
- A building-by-building inspection lists the failed joints.
- You get a fixed quote, per block or for the whole programme.
- Dates and areas are agreed so occupiers can be told.

- Joints are resealed and tooled.
- Each building is checked and signed off with the 12-month guarantee.
Getting the site ready

Advice
Aftercare for building managers
Keep the joints in good shape with a few simple steps:
- Include mastic in your cyclical inspections
- Make it easy for occupiers to report draughts
- Start inspections with the most exposed faces
- Share your contractor requirements early
Encourage occupiers to report water or draughts at frames. A quick report keeps a small repair small.
Joints on a building age together, so it pays to look at the whole elevation. A planned reseal saves repeated visits.
Why deal with it now?
Open external joints let water into walls and around frames. Damp patches, stained plaster and decorating claims can follow, which is harder to deal with than resealing. Older rural buildings around Woodgreen move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
The price depends on how many linear metres there are, what has to come out first and how the joints are reached. Call for a quote when you are ready.

Do you take on block-wide or estate-wide mastic work in Woodgreen?
Yes, we quote for single buildings and for programmes across several blocks. Residents are given notice through you, and the work moves building by building.
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’ll confirm with the quote.

Yes. Woodgreen is in our area. To discuss a job, ring 01277 525 020 or send details through our quote form.
Who decides which product is used?
The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Will residents or tenants be disturbed?
Residents and tenants carry on as normal. If any flats or units need access, we will tell you in advance so you can arrange it with occupiers.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
How the job changes by surface
Commercial and mixed-use buildings
Where retail and residential share a building the programme has to suit everyone. Tell us your site hours and access windows and we’ll plan around them.
Planned maintenance
Mastic wears out like any building component; how fast comes down to movement, weather, UV and the product. Inspecting joints regularly keeps programmes on track.
Looking after buildings in and around Woodgreen
Woodgreen is in the South East, one of the UK’s drier regions. External mastic still waits for dry faces and the right temperature, and the sunniest, most exposed sides of a building typically need attention first.
For a school such as Breamore Church of England Primary School, perimeter mastic on windows and doors is a holiday job. Historic properties like Breamore House, 1.5 miles north-west of Woodgreen, show the age of some local stock, where frame mastic must suit soft brick or stone. Landlords with units on estates such as Arch Farm Industrial Estate (to the south-west of Woodgreen) can bring frame, door and external mastic across several units into one programme.

Doing it in-house
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.
