How we handle facade sealing in Carshalton
Sealant around windows, doors and cladding panels stops rain reaching the wall behind. When a perimeter bead splits or peels, water finds its way behind frames and into the structure. We cut out failed facade joints and reseal them with a facade-grade sealant suited to the movement. Site teams most often ask us about perimeter sealant that has split or peeled away and hard, chalky sealant that no longer flexes, across shopfront frames, coping and flashing joints and window and door perimeters. Looking for mastic applicators who cover Carshalton? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
Every London site, Carshalton included, is inside the ULEZ, which applies to deliveries and contractors’ vans alike. Add booked delivery slots and limited storage, and a London mastic package needs planning before the first bead.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Different surfaces, different methods
Window and door perimeters
Perimeter joints move as frames expand and contract in the sun. The rod limits depth, leaving the bead able to flex.
Brick and stone facades
Brick and stone facades have perimeter and movement joints that need a compatible sealant. Neutral-cure products are used because acetoxy types can mark some stone, and primers go on where specified.

After the work
After handover, these steps help:
- Brief window cleaners about newly sealed joints
- Inspect facade joints on a regular cycle
- Don’t wait for a second leak before calling
- Record the product and colour used on each elevation
Look at perimeter and panel joints as part of routine building checks. Signs to look for are cracking, edges lifting, chalking and stiffness; record the locations.
Coordinate facade sealing with other external works. One set-up for several trades saves money.
FAQs: Carshalton
Can you work in a London building with booked loading and goods-lift slots?
Yes. Inductions, permits and timed loading are routine for us in London. The building manager’s rules go straight into our method. The ULEZ covers the whole of Greater London, which we allow for
Can work at a site such as University for the Creative Arts - Epsom fit around teaching?
Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
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 external work may be moved if conditions aren’t right. Internal work is far less affected.
What site paperwork can you supply?
Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.
Will you check whether the sealant is causing the leak?
Yes. Photos are often enough to start, followed by a visit if needed. Many frame leaks are sealant failures, though not all, and we’ll be honest about which it is.
Do you install glazing systems?
No. A glazing contractor handles that. What we seal are the joints around frames and panels on commercial buildings.
Can you work to our specification?
Yes. Send it with your enquiry, and we’ll price the work to it.
On site: what to expect
Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. All of Greater London is in the ULEZ, and kerbside space in Carshalton can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- We look at the joints, the drawings and the access before pricing.
- Failed sealant is cut out along its full length.
- Both faces are cleaned and, where the product needs it, primed.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- We walk the finished joints with you before handing over.
What we need from you
- Clear stock, furniture or equipment away from the joints
- Tell us your opening times and when work is allowed
- Send asbestos survey details if the building is pre-2000

Advice
How the quote is worked out
Each job is priced on its own details. The main factors are:
- Backing rod, priming and other preparation
- Access and working height
- Working within restricted access windows
- Removal of failed or old sealant
There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.
Details that help us quote
Whether it’s one area or a whole building, the same details help:
- Asbestos survey details if the building is older
- Photos of the joints, close up and from further back
- Rough lengths or quantities, or drawings if you have them
- Anything awkward about access or site hours
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.
Should maintenance staff do it?
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Mastic packages on Carshalton sites
Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in Carshalton. Deliveries are booked and storage is tight, so mastic materials come in as needed. The area within 2 miles of Carshalton holds a number of hotels. Hotel extensions and refits typically have to fit around bookings, so mastic dates are tight.
