How we handle facade sealing in Cold Harbour
Facade joints are the line of defence between the weather and the building fabric. Once a perimeter seal fails, water tracks in around frames and panels. We cut out failed facade joints and reseal them with a facade-grade sealant suited to the movement. The enquiries we see most involve previous reseals run over old sealant and air leaks through failed facade joints, on cladding panel joints, shopfront frames and coping and flashing joints. Facilities teams, main contractors and managing agents in Cold Harbour tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
In the countryside around places like Cold Harbour, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.
Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

What affects the price in Cold Harbour
We price every job individually. The things that drive the figure:
- How much there is to seal
- Specialist products, such as fire-rated or hygienic sealants
- How accessible the joints are
- Induction, permit and paperwork requirements
The product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site rules also count.
Details that help us quote

Different surfaces, different methods
Brick and stone facades
Stone can absorb plasticisers from the wrong sealant. The specified stone-compatible sealant is what we use.
Cladding panel joints
Where panels are sealed rather than open-jointed, the bead is part of the weather line. We cut out failed joints along their full length and rebuild them with backing and a facade-grade sealant.
Building and refurbishing in Cold Harbour
At about 42 miles from central London, Cold Harbour is within reach of the capital. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and each scheme needs its mastic sealed to programme. Cold Harbour sits in one of the drier corners of the country, the South East. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so external mastic is timed for workable conditions and agreed with the site manager.
Historic houses such as Belmont House and Gardens (to the north-east of Cold Harbour) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. Building work at universities like Canterbury Christ Church University (4.5 miles north-west of Cold Harbour) is often timed for the summer, mastic included.

Why it’s worth doing now in Cold Harbour
Topping up a failed joint typically buys very little time. A full cut-out and fresh bead is the repair that holds and avoids repeat call-outs. One visit to deal with every failing joint makes more sense than several trips to a place like Cold Harbour, rather than one at a time. Send photos of each area and we’ll quote for the lot.
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.
What you get with us

Your questions answered
Can work at a site such as Canterbury Christ Church University fit around teaching?
Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Is Cold Harbour too small for you to travel to?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.
Do we need an asbestos check before resealing?
For older buildings, yes, check before work starts. The dutyholder holds the asbestos register, and we will ask to see it. Suspect material is left alone until it has been tested.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
How do I request a quote?
The quote form is the simplest route, though you can also call the office on 01277 525 020 or email drawings and photos. Photos, drawings or a joint schedule help us quote quickly.
Can you work in cold or wet weather?
We can work through the year, but sealant needs a dry joint and temperatures within the product’s range. Frost and condensation on glass and steel are common on winter mornings.
Is any job too small?
Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.
After the work
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Inspect facade joints on a regular cycle
- Keep pressure washers away from fresh sealant
- Avoid patch repairs on failed facade joints
- Confirm the survey covers external sealants in older buildings
Record the sealant type and date on the building file. It helps when matching repairs or planning the next reseal without guesswork.
Planned resealing is cheaper than reacting to leaks. Inspect regularly and reseal sections as they start to fail instead of after the damage.
