Leave it or put it right?
The longer a failed joint is left, the more the substrate suffers: wet edges break down, so repairs may be needed before resealing. Acting at the first sign of splitting keeps the fix simple. Older rural buildings around Little London move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
The product called for affects the cost, and so does the preparation. Access, phasing and site rules also count.

Facade sealing in Little London, done properly
External joints face UV, rain, temperature swings and building movement all year. How long a joint lasts depends on the movement it takes, its exposure, the product and how well it was installed. When the time comes, we cut the old sealant out completely and start again. We work on perimeter joints where frames meet the structure, cladding panel joints and coping and flashing joints, and the usual reasons a site gets in touch are patch repairs that keep failing and old perimeter mastic that has dried out. For commercial sealant work in Little London, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Around smaller places like Little London, building work typically means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Work for main contractors and building owners
When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
What sealant work can’t fix
Sealant solves a lot, but not everything, and we are upfront when that’s the case. These need a different solution:
- Joints whose design needs changing by the specifier
- Water getting in through cracked render or porous masonry
- Arranging specialist high-level access, which is planned with the client
If in doubt, speak to us on 01277 525 020 or send details through our quote form and we will say what we think.
Where we work in Little London
- Window and door perimeters
- Shopfront frames
- Cladding panel joints
- Stone and brick facade joints
- Perimeter joints where frames meet the structure
- Coping and flashing joints
How the job changes by surface
Perimeter joints at frames and structure
These frame-to-structure joints take a lot of movement and weather. They are cut out, cleaned, backed and resealed using a sealant classified for that use.
Window and door perimeters
Perimeter joints move as frames expand and contract in the sun. Rod placed at the right depth lets the bead stretch.
Our process
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. If others near Little London need work, visits can be combined. A fixed quote is given before anything starts.
- Access, site rules and timing are settled with the client up front.
- We only seal when joints are dry and within the product’s temperature range.
- Each joint is cut out and the edges inspected.
- Faces are cleaned, primed where needed and backed.
- Facade-grade sealant goes in and is tooled to a tidy concave profile.
- We hand over with our 12-month workmanship guarantee.
Before we start on site
- Let building users know which areas are affected
- Let us know about inductions and permits
- Move anything stored against the joints

FAQs: Little London
Is a hospital such as Basingstoke and North Hampshire Hospital somewhere you can work?
Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.
Can you work at a site such as Berry Court Business Park, by Little London?
Yes. Estates, retail parks and business parks around Little London, Berry Court Business Park among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.
When can you be on site?
Mention the site’s hours and access windows in your enquiry, and we will schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.
Will your applicators have CSCS cards?
Yes. If you need card details for site access, let us know and we will send them with the quote.
Can you find out why a window is leaking?
Yes. Photos are often enough to start, followed by a visit if needed. Many frame leaks are sealant failures, though not all.
Can you just add new sealant on top?
No. Overlaying is a shortcut that peels away quickly. We remove the failed sealant, clean the faces, set the depth and reseal.
Can you work while the building is occupied?
In the majority of cases, yes. Phased work can be planned so areas stay in use, with each area protected and signed.
Maintenance after handover
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:
- Inspect facade joints on a regular cycle
- Never let anyone seal over old sealant
- Record the product and colour used on each elevation
- Confirm the survey covers external sealants in older buildings
Following storms, look inside for damp or staining near frames. An early report usually means a small reseal rather than a bigger repair.
Use each reseal to correct the joint: correct depth, proper backing and a sealant that can take the movement. A well-designed joint lasts longer than a like-for-like copy of a failed one.
Mastic packages on Little London sites
At about 45 miles from central London, Little London is within reach of the capital. Towns within reach of London tend to keep building, from flats to offices and schools, and main contractors there need mastic that keeps to the programme. The South East is one of the drier parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so we time external mastic for dry faces and agree it with the site team.
Historic houses such as The Vyne, 1.9 miles to the south-east of Little London, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. Units on estates such as Berry Court Business Park, under half a mile south-west of Little London, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. On a healthcare site such as Basingstoke and North Hampshire Hospital, 3.6 miles to the south of Little London, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.
