Construction mastic in Teddington, done properly
Getting a subcontractor through site induction should be simple. We are a Constructionline member and CHAS accredited, and every applicator holds a CSCS card, with public liability insurance in place. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We work on cladding and panel joints, window and door perimeters and sanitary and kitchen joints, and the failures we are asked to look at most are different trades sealing to different standards and caulk cracking where joints are moving more than expected. A single leaking joint is often how a building in Teddington 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.
A great deal of London construction is refurbishment of occupied or part-occupied buildings, alongside new blocks. Replacement windows, recladding and fit-outs leave perimeter and facade joints to seal, often next to people still using the building.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

New build and refits around Teddington
Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in Teddington. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for. There are plenty of hotels within about 2 miles of Teddington. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.
Extensions at sites like Teddington Memorial Hospital (to the west of Teddington) usually sit beside working departments, and the mastic follows strict access rules. On a campus such as St Mary's University, which lies north of Teddington, new teaching buildings and residences are usually built and refurbished around the academic year.
Teddington is about 5 miles west of Wimbledon, in Greater London. We send applicators to Teddington for mastic packages, handled exactly as we handle every other area. Across Greater London, 764 places are covered, Teddington among them. Our London page has more on work in that area.
Commercial sites across TW11, TW12, TW2 and TW1 are covered. Buildings on Station Road, High Street and Church Road are within our area. Teddington sits on or close to the A311 and A313.

Your questions answered
Does your area include sites such as Newmans Shipyard & Business Park, near Teddington?
Yes. Our area takes in Teddington and its surroundings, with estates and business parks such as Newmans Shipyard & Business Park included. Photos and a short description are enough for a first look.
Do you work in London buildings with loading restrictions?
Yes, most London buildings have access rules of some kind, and we plan around them. The building manager’s rules go straight into our method. We allow for the ULEZ, which covers every borough
How do I request a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.
What hours do you work?
We’re in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.
What do you charge?
Each job is quoted on its own details. To get one, ring 01277 525 020 or email the details over with a description of the work.
Can you work to our specification?
The specified product is what goes in. If we think an alternative would suit better, we put it to you first.
Is it fine to apply new sealant on top of old?
No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
Honest limits
Not every problem is a sealant problem, and we’re upfront when that’s the case. It won’t fix:
- Designing joint widths or choosing the specification (that sits with the designer)
- Deciding which fire-stopping product a penetration needs
- Joints damaged after sign-off by following trades
Not sure which it is? You can phone 01277 525 020 or send details through our quote form and we will tell you honestly before you book.
What we seal
- Cladding and panel joints
- Brick and block movement joints
- Internal decorators’ caulk
- Window and door perimeters
- Sanitary and kitchen joints
- Floor and skirting junctions
General trades versus a specialist
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
Quoting for work in Teddington
Each job is priced on its own details. The main factors are:
- The size and state of each joint
- How much existing material needs removing
- Phasing around occupants
- Distance, for remote addresses
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 you’ll have a fixed figure to work with.
Sending details for a quote
There’s no need for a formal survey. These details are enough to start:
- Asbestos survey details if the building is older
- Approximate linear metres or a joint schedule
- Whether the building will be occupied during the work
- Specification clauses that apply
Let us know the site, the scope and your timescale, and we’ll put a fixed quote together. To get it moving, phone 01277 525 020 or email drawings and photos.
How the job changes by surface
External facade and movement joints
Many facade substrates need a primer before sealing. We prime where the manufacturer specifies.
Internal decorators’ caulk
Where the specification calls for it, acrylic decorators’ caulk goes on non-moving internal gaps before painting. It’s for gaps that stay still and get painted, and we use a flexible sealant where there’s movement.
Signs you need construction mastic in Teddington
Three-sided adhesion is a frequent fault on new work. Bonded to the base of the joint and both sides, sealant can’t stretch evenly.
Clients usually get in touch after noticing something like this:
- Frame perimeters left unsealed or poorly sealed
- Early adhesion failures on new external joints
- Inconsistent sealant finishes from plot to plot
- Frame gaps too wide for sealant alone
For contractors at a college like Kingston College Creative Industries Centre, 1.6 miles to the south-east of Teddington, perimeters and internal sealant are timed for the holidays.
What to look for in a quote
- The named product and why it was chosen
- How the joint faces will be prepared and primed
- How they’ll work around occupants
- Proof of insurance
Diagnose, treat, sign off
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work usually takes anything from a day of snagging to several weeks of plot-by-plot sealing on a phased scheme, and our waste is bagged and taken away as we go. Most London premises stay occupied while we’re on site, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.
- We start with the drawings, specification and programme.
- Quantities are measured and a fixed price returned.
- The sequence is agreed with the site manager.
- Each area is sealed when it’s released.
- Joints are prepared, backed and sealed to the specification.
- After snagging, the work is handed over under our 12-month guarantee.
What we need from you
- Tell staff and tenants when we will be in
- Share the asbestos register for older buildings
- Share your working hours and any access restrictions
