Keeping the joints sound
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Report water ingress at frames as soon as it shows
- Share access with other external trades
- Confirm the survey covers external sealants in older buildings
- Inspect facade joints on a regular cycle
If new signage, brackets or services are fixed through a sealed joint, the seal needs making good. Make sure the joint is resealed afterwards with a compatible product.
Get the joint design right when resealing: correct depth, proper backing and a sealant that can take the movement. Repeating a faulty detail just repeats the failure.
Facade sealing for commercial buildings in Teddington
We are often asked to look at water coming in around frames. Very often the perimeter bead has cracked or lost its grip, though that isn’t the only cause. If the evidence points away from the sealant, we say so before quoting. If you have staining on stone next to old sealant and hard, chalky sealant that no longer flexes, we can put it right, whatever the surface. A specialist sealant contractor works differently from a general builder: on jobs in Teddington, preparation and product choice get the time they need.
Building sites in London tend to be tight: limited storage, booked deliveries and access shared with other trades. Mastic is typically one of the last trades on each elevation or floor, so we keep to the programme and the order of trades the site sets.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

What the job involves on each surface
Coping and flashing joints
Where the specification calls for sealant at copings or flashings, we can seal them. They sit in the most exposed positions on the building and need a durable external sealant.
Brick and stone facades
On masonry, the sealant has to suit a porous, textured surface. Neutral-cure products are used because acetoxy types can mark some stone.
How a job runs
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- We start with photographs, drawings or a visit to see the joints and agree access.
- We confirm the joint type, movement and the specified product.
- The existing bead comes out in full.
- Primer is applied where the maker specifies it.
- Backing rod is fitted and the new sealant gunned in and tooled.
- We go over the completed work with you before leaving.
Getting the site ready
- Tell us what induction or permit system the site runs
- Share your working hours and any access restrictions
- Tell staff and tenants when we’ll be in

What we are called out for in Teddington
Adhesive failure, where the sealant peels away from one face, usually comes from poor preparation. Contamination, moisture or skipping the primer the maker specifies leave a weak bond, and the joint opens with the first real movement.
Look out for the following:
- Unsightly perimeter sealant on a visible elevation
- Sealant pulling away from frames or panels
- Weathered facade joints that have lost their grip
- Gaps between rainscreen or cladding panels
New units and refits on sites such as Newmans Shipyard & Business Park (to the north of Teddington) need their panel and perimeter joints sealed to the specification.
What to look for in a quote
- Their plan for phasing and protecting the area
- Will CSCS-carded applicators be on site?
- Whether old or failed sealant will be cut out, not overlaid
- What the guarantee covers, and for how long
Leave it or put it right?
Resealing a few window perimeters is a small job; repairing water-damaged interiors and fixings is not. Leaks travel along the structure. In a London building, a failed joint rarely affects only one party: water travels through shared structures, and a small leak becomes a dispute between occupiers. Putting it right early is less disruptive than dealing with the consequences.
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.

When something else is needed
A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is any of the following:
- Work on the window or framing system itself
- Movement beyond what any sealant can handle
- Damp caused by condensation inside the building
If you’re not sure, just speak to us on 01277 525 020 or email a schedule or drawings and we will give you a straight answer.

Your questions answered
Will you plan work around the academic year at somewhere like St Mary's University?
Yes, holiday working periods are the norm on campus jobs. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Is Newmans Shipyard & Business Park, near Teddington, within your area?
Yes. Our area takes in Teddington and its surroundings, with estates and business parks such as Newmans Shipyard & Business Park included. To start, just ring 01277 525 020 or use the quote form with the unit, the joints involved and your access times.
What do you charge?
Every job gets its own fixed quote. To get one, call the office on 01277 525 020 or email drawings and photos.
Can weather delay the job?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.
How long does a typical visit take?
We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.
Can you handle several sites?
Yes. A group of buildings can go on one quote, and you deal with one contact throughout across South East England, Greater London and Scotland.
Can you find out why a window is leaking?
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.

Teddington has a good number of hotels close by, all within 2 miles. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades. Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in Teddington. Delivery slots and scarce storage shape how and when the mastic goes in.
Further education sites such as Kingston College Creative Industries Centre (1.6 miles south-east of Teddington) are extended and refurbished from time to time, with mastic often programmed into the summer break. University estates such as St Mary's University (0.7 miles north of Teddington) tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal.
