Mastic sealing in Westenhanger
Older blocks and commercial buildings can have mastic that contains asbestos. We check the asbestos register or survey before any old sealant is cut out and if it’s suspected, work stops until it’s tested. We don’t remove asbestos-containing materials. If you have a mix of products and colours from past repairs and no planned programme for sealant, we can help, on communal entrances and stairwells, shopfronts below residential blocks and external wall and movement joints alike. Searching for sealant specialists in Westenhanger? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
For buildings around smaller places like Westenhanger, we group work so one trip covers it. Photos of each elevation help us quote accurately.
The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Signs you need mastic sealing in Westenhanger
Much failed sealant was laid on dirty, dusty or damp surfaces. Without clean, sound faces and a primer where the product needs one it comes away from one face.
It’s worth sending us details if you spot any of the following:
- Estate-wide sealant that is simply worn out
- Draughts at frames across a block
- Damaged joints in communal entrances and corridors
- Leaks at window and door perimeters
With historic buildings such as Westenhanger Castle (to the north-west of Westenhanger) in the wider area, owners of older properties around Westenhanger should expect mastic to need a product that suits old masonry.

Doing it in-house
Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Related advice
Aftercare for building managers
Problems stay small when the joints are checked regularly. In particular:
- Check sealant joints during planned building inspections
- Keep bins and bikes away from communal door frames
- Log resealing dates block by block
- Make it easy for occupiers to report draughts
Log the date and extent of the resealing for each block. It helps plan the next round and gives you a history.
Planned resealing is easier to budget than emergency repairs. A programme can start with the worst buildings so spending is spread.
Different surfaces, different methods
Planned maintenance
Planned resealing replaces emergency callouts and keeps budgets predictable.
Commercial and mixed-use buildings
Commercial buildings have mastic at shopfronts, entrances and external joints. We work across portfolios on a planned basis.
Your questions answered
Is Westenhanger too far out for you?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
Do you work in occupied care homes around Westenhanger?
Yes. Care settings are planned area by area, at times agreed with the home. Tell us about any infection-control or safeguarding requirements and we will work to them.
How do I request a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
What guarantee do you give on resealing?
Every building we reseal has a 12-month guarantee. It covers our workmanship, not later building movement, damage or frame failures.
How soon can the area be used again?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
Does weather matter for sealant work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
