Mastic sealing in Lee Common
We diagnose before we prescribe: 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, with backing rod setting the depth where it’s needed. The enquiries we see most involve cracked, hardened mastic round windows on a block and draughts at frames across a block, on shopfronts below residential blocks, window and door perimeters on blocks and communal entrances and stairwells. For commercial sealant work in Lee Common, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Owners and agents with buildings around smaller places such as Lee Common 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.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Owners, agents and contractors
Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.
What we can’t put right
A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is any of the following:
- Frames that are rotten, warped or broken
- Masonry that has broken away beside the joint
- Asbestos-containing sealant, which we don’t remove
If you are not sure, just phone 01277 525 020 or use the quote form and we will give you a straight answer.

Mastic sealing in Lee Common: the local picture
Rainfall across the South East, Lee Common included, is lower than in many parts of the UK. External mastic still waits for dry faces and the right temperature, and the sunniest, most exposed sides of a building normally need attention first. Central London is about 30 miles from Lee Common. Managed blocks of flats are a big part of commuter-belt property; their frame mastic often ages block-wide.
With historic buildings such as Cholesbury Manor House (2.3 miles north-east of Lee Common) in the wider area, owners of older properties around Lee Common should expect mastic to need a product that suits old masonry. If you are responsible for a building such as St Mary's, frame and door mastic needs the same attention as any other property. Site managers at schools like Lee Common Church of England School can fit frame mastic into the summer works.

Then we strip out anything that has failed, prepare every joint and seal it. Jobs in and around smaller places like Lee Common are usually planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

Advice
When to bring in a specialist
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
FAQs: Lee Common
Is Lee Common too small for you to travel to?
Not at all. Lee Common is within our area. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Do you take on block-wide or estate-wide mastic work in Lee Common?
Yes. Portfolio-wide programmes are a regular request. We can phase the programme to suit your budgets and notice periods.
Do you work for managing agents and housing associations?
We do. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords, and we quote building by building or as a programme.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it.
Does weather matter for sealant work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
How do you choose the sealant?
The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
What about access for upper-floor joints?
It depends on the building. How upper joints are reached is agreed before work is booked so there are no surprises.

How the job changes by surface
External movement joints
External movement joints take up expansion and contraction. Failed sealant in a movement joint lets water in.
Estate-wide resealing programmes
Housing associations and agents often manage many similar blocks. We quote building by building and work through them in turn.
After the work
Your facilities or cleaning team can help the joints last. Pass these on to them:
- List the paperwork your organisation requires when you send details
- Share the asbestos register when you send details
- Make mastic part of routine maintenance checks
- Encourage occupiers to report problems at frames
Keep records of when each building was resealed. It helps plan the next round and gives you a history.
One failed perimeter usually means others on the same building are close so a single failure is a sign to check the rest. Doing them together saves going back again and again.
