General trades versus a specialist
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
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.
Facade sealing for commercial buildings in Twickenham
External sealing depends on the weather more than most trades. The sealant needs a dry joint and temperatures inside the maker’s limits, and cold, damp starts can delay work. We plan for that and keep you updated. Site teams most often ask us about failed seals around shopfront and entrance frames and failed sealant on precast panel joints, on coping and flashing joints, cladding panel joints and perimeter joints where frames meet the structure. A specialist sealant contractor works differently from a general builder: on jobs in Twickenham, preparation and product choice get the time they need.
Building sites in London tend to be tight: small compounds, delivery slots and shared hoists and scaffold. Mastic is normally 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 we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

What else we do in Twickenham
Our process
Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then reopened once the sealant allows before we move to the next. In Twickenham, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.
- Photos, drawings or a visit tell us about the joints and the access.
- Product choice follows the joint’s movement and substrate.
- The existing bead comes out in full and the joint faces cleaned.
- Primer goes on where the product data asks for it.
- Backing rod is fitted and the new sealant gunned in and tooled.
- We go over the completed work with you before leaving.
What we need from you
- Share the asbestos register for older buildings
- Explain the parking and delivery arrangements
- Tell us which areas need to stay in use

Keeping the joints sound
For the best life from the joints:
- Check that rainwater leaves the facade the way it was designed to
- Don’t wait for a second leak before calling
- Confirm the survey covers external sealants in older buildings
- Avoid harsh cleaners on facade sealant
Keep a note of which product went in and when. It helps when matching repairs or planning the next reseal.
In pre-2000 buildings, check the asbestos register before old sealant is cut out. Older sealants can contain asbestos.
Common problems we fix in Twickenham
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.
Site and facilities staff are often the first to spot these:
- Gaps between rainscreen or cladding panels
- Discoloured or dirty facade joints
- Old perimeter mastic that has dried out
- Failed seals around shopfront and entrance frames
University estates such as St Mary's University (0.8 miles south of Twickenham) tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal.

Common questions from Twickenham clients
Do you cover business parks and estates near Twickenham, such as Heathlands Industrial Estate?
Yes, sites like Heathlands Industrial Estate are within our area, along with the rest of Twickenham. A few photographs and the unit address let us price the work.
Can work at a site such as St Mary's University fit around teaching?
Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Do you replace windows or glass?
No. A glazing contractor handles that. What we seal are the joints around frames and panels.
How do we ask for a quote?
You can use the quote form on this site; alternatively, call the office on 01277 525 020 or use the quote form. Photos, drawings or a joint schedule help us quote quickly.
Do you run new sealant over the existing bead?
No. Overlaying is a shortcut that peels away quickly. We remove the failed sealant, clean the faces, set the depth and reseal.
How soon can the area be used again?
Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.
Can the building stay open while you work?
In most cases, yes. We phase the work so most of the building stays in use.
Facade sealing in Twickenham: the local picture
Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in Twickenham. Deliveries are booked and storage is tight, so mastic materials come in as needed. A good number of hotels sit less than 2 miles from Twickenham. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
Work at a hotel such as London Marriott Hotel Twickenham, 0.5 miles north of Twickenham, tends to be programmed around bookings, mastic included. Recladding or extending a unit at a site like Heathlands Industrial Estate, under half a mile south of Twickenham, brings panel joints and frame perimeters into the programme.

What the job involves on each surface
Cladding panel joints
Joints between cladding panels open and close with temperature. We use a product rated for the movement and suited to the panel surface, often a low-modulus silicone or hybrid.
Coping and flashing joints
Where the specification calls for sealant at copings or flashings, we can seal them. These joints take full exposure to weather, so preparation and product choice matter.
