Mastic sealing across Tooting
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
When to bring in a specialist
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
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.
Mastic sealing in Tooting
There isn’t one mastic for every joint on a building. Window perimeters and external joints often take a low-modulus neutral-cure silicone, and MS polymer sealants stick well to many substrates and often take paint. We’ll confirm the colours available for the specified product. We work on window and door perimeters on blocks, communal kitchens and washrooms and external wall and movement joints, and what we’re called in for most is repeated reactive repairs to the same buildings and estate-wide sealant that is simply worn out. Facilities teams, main contractors and managing agents in Tooting tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Planning mastic work on a London block means notices to residents, access to flats and agreed working areas. We work to the agent’s notice and access plan, so residents know what’s happening.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Quoting for work in Tooting
Quotes vary with the job. It mainly depends on:
- How much there is to seal
- The product specified
- Access and working height
- Joint width, depth and condition
The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
Details that help us quote
Whether it’s one area or a whole building, these details speed things up:
- How the joints are reached, and at what height
- What the building is and how it’s used
- The postcode of the building
- The product your specification calls for

When to call us in Tooting
Occasionally the substrate fails, not the sealant, such as crumbling render, brick arrises or frame edges. We will tell you if the joint edges need repairing before resealing.
Look out for the following:
- The same joint failures repeated across a portfolio
- Brittle perimeter mastic across a building
- Water getting in round frames after rain
- Movement joints with sealant missing
For agents with blocks near Tooting station (0.6 miles south of Tooting), a block-wide mastic programme deals with frames, balconies and entrances in one go.
What to look for in a quote
- Their pre-qualification and accreditations
- Whether primer will be used where the manufacturer specifies it
- How long is the guarantee, and what does it include?
- Whether old or failed sealant will be cut out, not overlaid
On site: what to expect
Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. For a job in Tooting, access comes first. Give us the hours we can be on site and we will schedule to suit.
- We inspect each building and record the joints that have failed.
- The quote is fixed and split as suits you.
- We agree the programme and dates with you.
- Old mastic is removed and the joint faces prepared.
- New sealant goes in with backing rod and primer where needed.
- We check the finished work and confirm the guarantee.
What we need from you
- Share the asbestos register for older buildings
- Clear stock, furniture or equipment away from the joints
- Share your working hours and any access restrictions
Getting a fixed quote
Send us photos, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.

Looking after the joints
Once the work is signed off, these steps help:
- Share the asbestos register when you send details
- Share your contractor requirements early
- Look at the sunniest and most exposed elevations first
- Protect low-level joints in entrances
Include sealant in planned building inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away and record where they are.
Planned resealing is easier to budget than emergency repairs. A programme can start with the worst buildings and work down the list.
Honest limits
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Frames that are rotten, warped or broken
- Materials that need asbestos testing before work
- Masonry that has broken away beside the joint
If in doubt, call the office on 01277 525 020 or email drawings and photos and we’ll say what we think before you book.
Joints and surfaces we work on
- Balcony and threshold joints
- Communal kitchens and washrooms

Questions about Tooting
Will you work in a care home in Tooting without moving residents out?
Yes, with the manager deciding the order and timing of rooms. Tell us about any infection-control or safeguarding requirements and we’ll work to them.
Do you work in London buildings with loading restrictions?
Yes, we plan every London job around the building’s own access rules. The building manager’s rules go straight into our method. All of Greater London is inside the ULEZ, and our planning allows for it
Do you supply RAMS and insurance details?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are CHAS accredited and a Constructionline member.
Can you quote from photos?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Does the weather affect the work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
What about access for upper-floor joints?
Every block is different. We agree access with you at quote stage so the fixed quote reflects it.
