Why it’s worth doing now in Cold Harbour
Open facade joints also let air and dirt through: draughts around frames add to heating costs and complaints. A new seal closes the gap for both. Older rural buildings around Cold Harbour move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we will explain how it’s made up.

Facade sealing in Cold Harbour, done properly
Our facade sealing work covers external facade joints, window and door perimeters, cladding panel joints and the perimeter joints where frames meet the structure. Coping and flashing joints are included where sealant is the specified fix. If you are dealing with air leaks through failed facade joints and failed sealant on precast panel joints, we can put it right, whatever the surface. A single leaking joint is often how a building in Cold Harbour first comes to us: we look at the rest while we are there and tell you what we find.
Around smaller places like Cold Harbour, building work normally means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
Work we carry out comes with a 12-month guarantee. If an installation problem shows up, call the office on 01277 525 020 or email drawings and photos and we will arrange a return visit.

Doing it in-house
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
Commercial clients in Cold Harbour
When you manage a building on behalf of an owner, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.
Sites and facades in and around Cold Harbour
Cold Harbour is in the South East, one of the UK’s drier regions. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so we time external mastic for dry faces and agree it with the site team. At about 30 miles from central London, Cold Harbour is within reach of the capital. Towns within reach of London tend to keep building, from flats to offices and schools, and main contractors there need mastic that keeps to the programme.
Projects at colleges like Berkshire College of Agriculture (to the north of Cold Harbour) tend to run to term dates, so the mastic is planned tightly. On a healthcare site such as St Mark's Hospital, which lies north-east of Cold Harbour, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. With historic properties like Harleyford Manor, 3.3 miles to the north of Cold Harbour, in the area, refurbishment work often meets old masonry that needs compatible sealants.

Questions we’re asked in Cold Harbour
Can work at a site such as Berkshire College of Agriculture fit around teaching?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Is Cold Harbour off your patch?
Not at all. Cold Harbour is within our area. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.
Is the work guaranteed?
Yes. Our workmanship is backed for 12 months on every job.
Who decides which product is used?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Will your applicators have CSCS cards?
Yes. Our applicators hold CSCS cards, which many sites require.
Is colour matching possible?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We will confirm the colours available for the specified product.
Will you check whether the sealant is causing the leak?
Yes. Photos help, and you can phone 01277 525 020 or use the quote form to arrange a visit. Many frame leaks are sealant failures, though not all, and we will tell you which.
What the job involves on each surface
Window and door perimeters
Perimeter joints move as frames expand and contract in the sun. The rod limits depth, leaving the bead able to flex without tearing.
Render and coated surfaces
Rendered and painted facades need a sound edge for the sealant to bond to. Loose coatings are cleaned back first, and areas needing repair are flagged.
How the quote is worked out
We price every job individually. The main factors are:
- Which sealant the job calls for
- Any access equipment needed
- Removal of failed or old sealant
- Backing rod, priming and other preparation
The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.
What to include in your enquiry
The more we know, the firmer the quote. When you get in touch, include:
- The postcode of the building
- When you need the work done
- A wide shot and a close-up of the area
- What the building is and how it’s used
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. For smaller jobs, photographs and a description will do.
