Mastic sealing in Coombe
Owners and agents normally inherit a building’s mastic rather than choose it, and it ages quietly: it sits round windows and doors, along external joints and through communal areas. When it hardens, splits or pulls away, water and draughts follow along with complaints. We work on communal entrances and stairwells, external wall and movement joints and window and door perimeters on blocks, and the usual reasons a site gets in touch are cracked, hardened mastic round windows on a block and open joints in brickwork or panels. Searching for sealant specialists in Coombe? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
For owners with a single building near Coombe, we plan to finish in one visit where possible. Send photographs of the frames and joints and we’ll give a fixed quote.
Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

What else we do in Coombe
When to bring in a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
How a job runs
When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself typically taking a day or two for a single block, longer for an estate programme. Smaller jobs around Coombe can be grouped with others nearby. You’ll have a fixed quote before work starts.
- First comes a look at the joints and, for older buildings, the asbestos records.
- The products and programme are set out in a fixed quote.
- Failed mastic is removed completely.
- Joint faces are cleaned, backed and resealed.
- Buildings are completed in turn.
Before we start on site
- Warn occupants and staff about the work
- Let us know about inductions and permits
- Explain the parking and delivery arrangements

Your questions answered
Can you quote for a block close to Little Kimble station?
Yes, and several blocks can go on one quote. Photos of each elevation help us quote accurately.
Is Coombe off your patch?
No. Places such as Coombe are covered as much as the big towns. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.
How soon can the area be used again?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.
Do you supply RAMS and insurance details?
Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We hold CHAS accreditation and Constructionline membership.
Who decides which product is used?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
What about access for upper-floor joints?
Every block is different. We agree access with you at quote stage so there are no surprises.
Will residents or tenants be disturbed?
Occupiers stay in the building throughout. We flag any areas that need internal access well before the dates so it can be arranged.
Planned mastic for Coombe portfolios
The South East is one of the drier parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and the sunniest, most exposed sides of a building usually need attention first. At about 34 miles from central London, Coombe is within reach of the capital. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres.

What the job involves on each surface

Tenants in commercial buildings need to keep trading so the work is phased.
Estate-wide resealing programmes
Priority order can follow condition, complaints or your maintenance plan. Quotes can be per block or for the full programme.
Common problems we fix in Coombe
Occasionally the substrate fails, not the sealant, such as crumbling render, brick arrises or frame edges. If the edges are unsound, we say so before quoting the sealing.
Clients normally get in touch after noticing something like this:
- Damaged joints in communal entrances and corridors
- Movement joints with sealant missing
- Complaints coming in block by block
- Cracked, hardened mastic round windows on a block
Trustees of buildings like Church of St Peter and St Paul can bring frame and external mastic into a planned maintenance list.
What your quote should include
- Is the sealant right for the movement and the substrate?
- How long is the guarantee, and what does it include?
- Whether old or failed sealant will be cut out, not overlaid
- How the joint faces will be prepared and primed
