About our mastic sealing in Shooter's Hill
Treatment starts with a proper look: which joints have failed, why, and whether sealant is the right answer. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in and backing rod used wherever a joint is deep. We work on communal entrances and stairwells, shopfronts below residential blocks and balcony and threshold joints, and what we are called in for most is patchy repairs in mismatched sealant and damaged joints in communal entrances and corridors. Searching for sealant specialists in Shooter's Hill? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
London’s ULEZ covers every borough, and parking and loading rules vary street by street. For block-wide work, a place to park and store materials saves time on every visit.
Every job we finish is backed by a 12-month workmanship guarantee, in Shooter's Hill as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Honest limits
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Broken glass or failed sealed units
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
Not sure which it is? You can ring 01277 525 020 or email us and we’ll tell you honestly.
Surfaces we seal
- Shopfronts below residential blocks
- Communal kitchens and washrooms
- External wall and movement joints
- Balcony and threshold joints
- Window and door perimeters on blocks
- Communal entrances and stairwells
Should maintenance staff do it?
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Looking after the joints
Keep the joints in good shape with a few simple steps:
- Ask residents or tenants to report leaks and draughts early
- Share your contractor requirements early
- Reduce knocks to communal area joints
- Track which buildings were done and when
Encourage occupiers to report water or draughts at frames. Early reports catch failures before damage spreads.
Mastic fails gradually, then all at once in a wet spell. Resealing when cracking first shows avoids water damage and saves internal repairs.

Common problems we fix in Shooter's Hill
We often find joints filled solid with no backing rod, so the mastic is glued to the joint bottom too. It can’t stretch properly and splits as the building moves.
Look out for the following:
- Communal area joints that look neglected
- Draught complaints from residents or tenants
- Cracked, hardened mastic round windows on a block
- Open joints in brickwork or panels
If you own or manage units on a site such as Gateway Business Centre, 1.7 miles north of Shooter's Hill, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.
Before you book anyone
- What the guarantee covers, and for how long
- Health and safety accreditation such as CHAS
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Whether primer will be used where the manufacturer specifies it
Diagnose, treat, sign off
On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, with the work itself normally taking anything from a day to a few weeks, depending on the number of buildings and joints. Most London premises stay occupied while we’re on site, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.
- A building-by-building inspection lists the failed joints.
- You get a fixed quote, per block or for the whole programme.
- We agree the programme and dates with you.
- Failed sealant is removed and the faces prepared.
- New sealant goes in with backing rod and primer where needed.
- Each building is checked and signed off with the 12-month guarantee.
Getting the site ready
- Send asbestos survey details if the building is pre-2000
- Tell us which areas need to stay in use
- Let building users know which areas are affected

What if the old mastic contains asbestos?
In older buildings, old mastic can contain asbestos. We ask for the asbestos register or survey before work starts and suspect material is tested first.
How do you choose the sealant?
A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.
How soon can the area be used again?
We will confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.
