Mastic sealing in Shawford
Treatment starts with a proper look: which joints have failed, why, and whether sealant is the right answer. Failed mastic is stripped, the faces taken back to sound material, primed where the manufacturer specifies and resealed and backing rod used wherever a joint is deep. The enquiries we see most involve worn sealant at communal door frames and window mastic that has split and shrunk, on communal entrances and stairwells, balcony and threshold joints and window and door perimeters on blocks. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Shawford, preparation and product choice get the time they need.
Owners and agents with buildings around smaller places such as Shawford 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.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Mastic sealing around Shawford: what changes locally
Rainfall across the South East, Shawford included, is lower than in many 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. At about 63 miles from central London, Shawford is within reach of the capital. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres, and window and balcony mastic on them tends to age at the same rate.
Site managers at schools like Compton All Saints Church of England Primary School can fit frame mastic into the summer works. Student accommodation around universities such as University of Winchester, 2.6 miles north of Shawford, is typically managed block by block, which suits a planned mastic programme.
Shawford is about 3 miles south of Winchester, in Hampshire. Shawford sits inside our coverage and the rest of Hampshire, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. We work across 723 places in Hampshire, from busy centres to rural villages. Sites around Southampton have their own page, roughly 8 miles from Shawford.

When to call us in Shawford
Previous repairs often sealed new mastic over old. New sealant won’t grip failed sealant and the repair soon fails.
It’s worth sending us details if you spot any of the following:
- Cracked, hardened mastic round windows on a block
- Damaged joints in communal entrances and corridors
- Damp patches beside frames
- Open joints in brickwork or panels
Buildings close to stations like Shawford station, less than half a mile to the south-west of Shawford, are often flats over shops, with frame mastic to keep sound.
What your quote should include
- Their approach to joint depth and backing
- What level of public liability insurance do they hold?
- Do they follow the manufacturer’s priming guidance?
- Will CSCS-carded applicators be on site?
When to bring in a specialist
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
Leave it or put it right?
Piecemeal repairs over the years often leave mismatched sealant. Resealing a whole building gives a consistent finish and one 12-month guarantee. For buildings around smaller places like Shawford, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.
Why us?
- A fixed quote before work starts

Your questions answered
Can you work at a site such as Hazeley Enterprise Park, by Shawford?
Yes, sites like Hazeley Enterprise Park are within our area, along with the rest of Shawford. Photos and a short description are enough for a first look.
Is Shawford off your patch?
No. Small places get the same service as large ones. We work across Greater London and the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
When can the area be used after sealing?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
Can you work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.
Do you supply RAMS and insurance details?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We hold CHAS accreditation and Constructionline membership.
Can you plan resealing across several buildings?
Yes. We survey and price each building, then work through them in order, and the programme can start with the worst.
Can you take on resealing for a block portfolio?
Yes, that’s exactly who this service is for. Buildings are scheduled in turn so you can plan around it.
When something else is needed
A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is one of these:
- Frames that are rotten, warped or broken
- Masonry that has broken away beside the joint
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
If in doubt, phone 01277 525 020 or email the details over and we’ll say what we think.
