Mastic sealing in Tooting Bec
Managing agents and housing associations normally need paperwork before anyone starts. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We’re a Constructionline member and CHAS accredited, and we carry public liability insurance. The enquiries we see most involve damp patches beside frames and open joints in brickwork or panels, on external wall and movement joints, balcony and threshold joints and communal kitchens and washrooms. A single leaking joint is often how a building in Tooting Bec first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Across Greater London, Tooting Bec included, the ULEZ applies, and parking and loading rules differ from street to street. For a block or estate, it helps to know where we can park and stage materials.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application.

On site: what to expect
Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. Planning a London job such as one in Tooting Bec starts with access: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.
- 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.
- Old mastic is removed and the joint faces prepared.

- Each building is checked and signed off with the 12-month guarantee.
Before we start on site

Do you need mastic sealing in Tooting Bec?
Previous repairs often sealed new mastic over old. New silicone has nothing to grip on old silicone, so these repairs rarely last.
It’s worth sending us details if you spot any of the following:
- Failed external movement joints
- Draughts at frames across a block
- Leaks at window and door perimeters
- Old repairs sealed over failed mastic
Owners of student blocks near University of the Arts London (3.3 miles north of Tooting Bec) can schedule frame and external mastic for the summer vacation.
Before you book anyone
- The named product and why it was chosen
- Whether primer will be used where the manufacturer specifies it
- What site paperwork they can supply
- Proof of insurance
Honest limits
Being straight saves everyone time. New sealant won’t cure:
- Substrate edges that need repairing first
- Glazing that needs replacing
- Failed window or door frames, which need a window contractor
If in doubt, phone 01277 525 020 or send photos by email and we will say what we think.
Joints and surfaces we work on

Cost factors for mastic joints
To price the job, we consider:
- Access and working height
- Specialist products, such as fire-rated or hygienic sealants
- The size and state of each joint
- The total length or number of joints
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.
What to include in your enquiry
We can often quote from photographs and a few details. Please tell us:
- Clear photographs of the problem areas
- Whether the building will be occupied during the work
- The postcode of the building
- Anything awkward about access or site hours
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.
When to bring in a specialist
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Your questions answered
Do you work in London buildings with loading restrictions?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. The building manager’s rules go straight into our method. All of Greater London is inside the ULEZ, and our planning allows for it
Can work in a care setting near Tooting Bec go ahead while residents are there?
Yes, with the manager deciding the order and timing of rooms. Any site rules, from signing in to infection control, are agreed before we start.
Does the weather affect the work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
Is Tooting Bec in your area?
Yes. We cover Tooting Bec, and you can phone 01277 525 020 or send photos by email to get started.
Who decides which product is used?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Can you send RAMS and CSCS details before starting?
We are CHAS accredited, a Constructionline member and carry public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
What will the job cost?
That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote.

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
