Leave it or put it right?
Patch repairs over old sealant tend to come back. A full cut-out and reseal costs more on the day but lasts much longer and avoids repeat call-outs. Halls, stores and units around places like Winterbrook may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

Facade sealing for commercial buildings in Winterbrook
Water ingress at window frames is a frequent reason facilities managers contact us. Very often the perimeter bead has cracked or lost its grip, though that isn’t the only cause. We will tell you if we think the leak is coming from somewhere sealant won’t fix. We work on perimeter joints where frames meet the structure, window and door perimeters and coping and flashing joints, and what we are called in for most is perimeter joints where frames meet the structure and gaps between rainscreen or cladding panels. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Winterbrook, preparation and product choice get the time they need.
For a site near Winterbrook, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Send drawings or photos and the programme and we’ll quote to suit.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

When to call us in Winterbrook
When the sealant tears down its centre, it has normally been asked to move more than it can. The joint may be too narrow, the bead too thin or the sealant the wrong movement class.
It’s worth sending us details if you spot any of the following:
- Air leaks through failed facade joints
- New sealant peeling off old mastic
- Unsightly perimeter sealant on a visible elevation
- Gaps between rainscreen or cladding panels
For contractors refurbishing units at places like Hithercroft Industrial Estate (1.3 miles north of Winterbrook), the mastic covers cladding panels, roller-door and window perimeters.

From enquiry to sign-off
Occupied buildings need a little choreography. 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. Smaller jobs around Winterbrook can be grouped with others nearby. You will have a fixed quote before work starts.
- Access, site rules and timing are settled with the client up front.
- Weather and temperature are checked against the product’s limits.
- Each joint is cut out and the edges inspected.
- Faces are cleaned, primed where needed and backed.
- Facade-grade sealant goes in and is tooled to a tidy concave profile.
- We hand over with our 12-month workmanship guarantee.
Preparing the site
- Move anything stored against the joints
- Share the asbestos register for older buildings
- Arrange parking or a loading space

Commercial clients in Winterbrook
Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so the building keeps working while we do.
FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
After the work
A few simple habits keep the new joints working:
- Walk the elevations once or twice a year
- Investigate damp beside windows promptly
- Insist on a full cut-out when joints are renewed
- Check the asbestos register before old mastic is disturbed
Record the sealant type and date on the building file. It helps when matching repairs or planning the next reseal.
Tie resealing in with redecoration, cladding repairs or other access. One set-up for several trades saves money and cuts time on site.
Common questions from Winterbrook clients
Is a hospital such as Wallingford Community Hospital somewhere you can work?
Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.
Is Winterbrook off your patch?
Not at all. Winterbrook is within our area. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.
Do you provide access for facade work?
We agree access with the client at the start. Let us know what access is in place or planned, and we will price the work around it.
Do you use silicone for external joints?
Most facade and window perimeter joints take a low-modulus neutral-cure silicone. Hybrid or MS polymer, polyurethane and polysulphide sealants suit others, as the specification or substrate requires.
Is old mastic on our building likely to contain asbestos?
For older buildings, yes, check before work starts. The dutyholder holds the asbestos register, so ask for it before we start. Suspect material is left alone until it has been tested.
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.

How the quote is worked out
Quotes vary with the job. Expect it to depend on:
- Travel to remote or island sites
- Removal of failed or old sealant
- How much there is to seal
- The product specified
What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a quote once you have the details.
What we need to price the job
There’s no need for a formal survey. A few details are enough to get going:
- The asbestos register, for older buildings
- When you need the work done
- Drawings or a marked-up plan, if available
- Where the site is, with the postcode
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.
