Mastic sealing in Ruxley
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
General trades versus a specialist
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.

Across Ruxley and the rest of Greater London, we work the same way: send details, get a fixed quote, we seal, and the work is guaranteed.

If you’re dealing with failed external movement joints and estate-wide sealant that is simply worn out, we can put it right, whatever the surface. Searching for sealant specialists in Ruxley? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.

After the work
Regular inspection catches problems early. Specifically:
- Look at the sunniest and most exposed elevations first
- Mention RAMS, insurance or CSCS requirements up front
- Track which buildings were done and when
- Share the asbestos register when you send details
Ask residents or tenants to report draughts or leaks round windows early. A quick report keeps a small repair small.
Budgets are easier to plan when sealant is part of planned maintenance. A programme can start with the worst buildings and work down the list.
Ruxley: questions and answers
Can you quote for a block close to Albany Park station?
Yes. Blocks of any size are within what we do. Photos of each elevation help us quote accurately.
Do you work in London buildings with loading restrictions?
Yes. Inductions, permits and timed loading are routine for us in London. Send the building rules and access times with your enquiry. All of Greater London is inside the ULEZ, and our planning allows for it
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.
Can you take on resealing for a block portfolio?
We do. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work, and we quote building by building or as a programme.
Is Ruxley in your area?
Yes. We cover Ruxley. For a quote, call 01277 525 020 or send details through our quote form.
Will you just go over the old sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.
How a job runs
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.
- We inspect each building and record the joints that have failed.
- The quote is fixed and split as suits you.
- Dates and areas are agreed so occupiers can be told.
- Failed sealant is removed and the faces prepared.
- Joints are resealed and tooled.
- Each building is checked and signed off with the 12-month guarantee.
Getting the site ready
- Warn occupants and staff about the work
- Share the asbestos register for older buildings
- Arrange parking or a loading space
Request a quote
Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

Common problems we fix in Ruxley
Buildings move with temperature and moisture, and the sealant takes up that movement. A joint that was too narrow, too thin or the wrong product can’t cope long before it should.
These are often picked up first by site or facilities staff:
- Leaks at window and door perimeters
- Communal area joints that look neglected
- Failed external movement joints
- Occupiers reporting cold air round windows
Older community buildings, St Botolph's Church among them, often have frames of mixed ages whose mastic varies.

What the job involves on each surface
Window and door perimeters on blocks
Blocks have a mix of frame materials, and the product is matched to the frame material and the masonry. Colours are confirmed for the product used.
External movement joints
Movement joints are cleaned out, backed with rod and resealed with a sealant of the right movement class.
Leave it or put it right?
Open external joints let water into walls and around frames. That can lead to damp, staining and damage to finishes and those cost far more to put right. Failed sealant in a building in Ruxley can quickly affect neighbours, tenants or the floor below. Putting it right early is less disruptive than dealing with the consequences.
A quote for mastic joints depends on how many there are, their condition and the access. Call for a quote.
