Facade sealing in South Town, done properly
Our facade sealing work covers external facade joints, window and door perimeters, cladding panel joints and the perimeter joints where frames meet the structure. Coping and flashing joints are included where sealant is the specified fix. Site teams most often ask us about failed seals around shopfront and entrance frames and previous reseals run over old sealant, on cladding panel joints, perimeter joints where frames meet the structure and window and door perimeters. Searching for sealant specialists in South Town? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
Construction in and around smaller places such as South Town is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
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.

Diagnose, treat, sign off
Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off.

- We plan access and the order of elevations with the client.
- We only seal when joints are dry and within the product’s temperature range.
- Each joint is cut out and the edges inspected.
- Joints are cleaned, primed if required and fitted with backing rod.
- Facade-grade sealant goes in and is tooled to a tidy concave profile.
- We hand over with our 12-month workmanship guarantee.

Advice
What we are called out for in South Town
New sealant run over old sealant rarely holds. Cured silicone won’t accept a new silicone bead, and the patch soon lifts.
Most enquiries start with something like this:
- Cladding panel joints that have opened up
- Air leaks through failed facade joints
- Unsightly perimeter sealant on a visible elevation
- Perimeter joints where frames meet the structure
Older buildings in the area around South Town, such as Bentworth Hall, 1.4 miles north-east of South Town, need care when sealed: the product has to suit soft or historic materials.
Questions to ask before you book
- How long is the guarantee, and what does it include?
- Their approach to joint depth and backing
- Which product they’ll use, and why it suits the joint
- Whether primer will be used where the manufacturer specifies it
Commercial clients in South Town
Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.
Honest limits
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Damaged frames that need replacing
- Arranging specialist high-level access, which is planned with the client
- Replacing glass or failed glazing units
If in doubt, call 01277 525 020 or email us and we’ll say what we think.

Mastic packages on South Town sites
South Town lies roughly 49 miles out from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, which keeps mastic packages in demand. The South East is one of the drier parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so we time external mastic for dry faces and agree it with the site team.
Extensions at sites like Alton Community Hospital (3.4 miles east of South Town) typically sit beside working departments, and the mastic follows strict access rules. School extensions, at buildings such as Medstead Church of England Primary School, usually run to the summer holidays, mastic included.
South Town is about 4 miles west of Alton, in Hampshire. Businesses, contractors and managing agents in South Town can call on us for facade joints, as part of our coverage of Hampshire. Our Hampshire coverage takes in 723 places, large and small. Southampton is covered too, some 20 miles away.

Aftercare for building managers
Once the work is signed off, these steps help:
- Record the product and colour used on each elevation
- Keep sills, gutters and drainage paths clear
- Check the asbestos register before old mastic is disturbed
- Don’t wait for a second leak before calling
Keep gutters, sills and drainage paths clear. Good drainage keeps water moving off the facade.
In pre-2000 buildings, check the asbestos register before old sealant is cut out. Older sealants can contain asbestos.

Common questions from South Town clients
Is hospital work, at somewhere like Alton Community Hospital, something you do?

Yes. We cover South Town and the area around it, including industrial estates, business parks and retail parks such as Lower Soldridge Business Park. Send details of the unit and the work through our quote form for a quick quote.
Do you install glazing systems?
No. A glazing contractor handles that. We reseal window perimeters, panel joints and frame-to-structure perimeters.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
How many days will you need on site?
That varies with the scale of the job, but the work typically takes anything from a single day to several weeks, depending on joint lengths, access and the weather. For bigger or phased jobs, we will set out a timescale with the quote.
What type of sealant goes on window perimeters?
The product follows the joint’s movement, the surfaces and the specification. BS EN 15651 Parts 1 and 2 cover facade and glazing sealants, and specifications often name them.
