Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
How the quote is worked out
We price every job individually. The main factors are:
- Whether old sealant has to be cut out first
- Phasing around occupants
- Which sealant the job calls for
- The total length or number of joints
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.
What to include in your enquiry
A good diagnosis starts with the right details. Let us know:
- Where the site is, with the postcode
- Asbestos survey details if the building is older
- Rough lengths or quantities, or drawings if you have them
- Your programme or deadline
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to call the office on 01277 525 020 or use the quote form with what you know.
Facade sealing for commercial buildings in Lee Common
External joints face UV, rain, temperature swings and building movement all year, and they wear out over time. Life depends on movement, weathering, product choice and the quality of the original work. When it fails, the whole bead is cut away and the joint rebuilt. Site teams most often ask us about unsightly perimeter sealant on a visible elevation and gaps between rainscreen or cladding panels, on perimeter joints where frames meet the structure, window and door perimeters and cladding panel joints. Looking for mastic applicators who cover Lee Common? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.
Sites around smaller places like Lee Common can be a fair drive from suppliers, so we come with everything the package needs. Drawings, photographs and the programme let us give a fixed quote.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

What happens if it’s left?
Each spell of rain drives water past a failed facade joint. Behind the frame, that can mean damp plaster, stained ceilings, corroded fixings and damaged insulation. Resealing now costs less than repairing interiors later. Around Lee Common, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Mastic packages on Lee Common sites
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 external mastic is timed for workable conditions and agreed with the site manager. Lee Common lies roughly 30 miles out from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and main contractors there need mastic that keeps to the programme.
For contractors on a campus like Buckinghamshire New University, which lies south-east of Lee Common, facade and perimeter sealing has to fit around students and term dates. For contractors at a school such as Lee Common Church of England School, sealing has to be finished before term starts. On a healthcare site such as The Chiltern Hospital, which lies south of Lee Common, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

On site: what to expect
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then handed back before the next one 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.
- Joints are cleaned, primed if required and fitted with backing rod.

- We hand over with our 12-month workmanship guarantee.

Advice
When something else is needed
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Joints too narrow for the movement they take, which need redesign
- Arranging specialist high-level access, which is planned with the client
- Installing or repairing glazing systems
Not sure which it is? You can give us a call on 01277 525 020 or use the quote form and we’ll tell you honestly.
Surfaces we seal
- Window and door perimeters
- Coping and flashing joints
- Shopfront frames
- Stone and brick facade joints
- Cladding panel joints
- Perimeter joints where frames meet the structure
Questions about Lee Common
Is a hospital such as The Chiltern Hospital somewhere you can work?
Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Will you plan work around the academic year at somewhere like Buckinghamshire New University?
Yes, holiday working periods are the norm on campus jobs. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Can you follow the specification on our project?
Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.
Are your applicators CSCS-carded?
Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.
Do you use silicone for external joints?
It depends on the joint, the substrate and any specification. Specifications often refer to BS EN 15651-1 for facade sealants or BS EN 15651-2 for glazing, and we work to what is specified.
Is any job too small?
Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.
Can the sealant be colour-matched?
That depends on the product specified. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.

After the work
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Insist on a full cut-out when joints are renewed
- Add perimeter sealant to planned maintenance checks
- Confirm the survey covers external sealants in older buildings
- Brief window cleaners about newly sealed joints
Look at perimeter and panel joints as part of routine building checks. Signs to look for are cracking, edges lifting, chalking and stiffness; note where they appear.
Check older buildings for asbestos before disturbing old mastic. Older sealants can contain asbestos, and if it’s suspected, we stop until it has been tested.
General trades versus a specialist
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
