Surface by surface
Planned maintenance
Mastic wears out like any building component; how fast comes down to movement, weather, UV and the product. Inspecting joints regularly keeps programmes on track.
Communal areas
Joints at low level in communal areas take knocks from bins, bikes and buggies, so they often need renewing sooner.
Mastic sealing in Coursehorn
Different joints need different sealants. Window perimeters and external joints often take a low-modulus neutral-cure silicone, while hybrid polymer sealants grip many materials and are often paintable, and colours are confirmed for whichever product is used. We work on shopfronts below residential blocks, external wall and movement joints and balcony and threshold joints, and the failures we’re asked to look at most are brittle perimeter mastic across a building and the same joint failures repeated across a portfolio. A specialist sealant contractor works differently from a general builder: on jobs in Coursehorn, preparation and product choice get the time they need.
Owners and agents with buildings around smaller places such as Coursehorn tend to manage small terraces of association properties, converted barns and commercial units. Frame and wall-joint mastic on all of them ages and hardens.
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.

When to bring in a specialist
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
What sealant work can’t fix
We check first that sealant really is the fix. It won’t put right:
- Glazing that needs replacing
- Masonry that has broken away beside the joint
- Leaks through the frame itself rather than the perimeter
If in doubt, call 01277 525 020 or email a schedule or drawings and we will say what we think before you book.
Surfaces we seal
- Window and door perimeters on blocks
- Communal entrances and stairwells
- Balcony and threshold joints
- External wall and movement joints
- Shopfronts below residential blocks
- Communal kitchens and washrooms
Leave it or put it right?
Failed perimeter mastic lets cold air in around frames, and they often blame the windows. Resealing the perimeters is often the simpler fix where the frames themselves are sound. One visit to deal with every failing joint makes more sense than several trips to a place like Coursehorn, rather than one at a time. Send photos of each area and we will quote for the lot.
There’s no price list, since every building and every scope is different. Call for a quote and we will price your job on its own details.

Looking after buildings in and around Coursehorn
Rainfall across the South East, Coursehorn included, is lower than in many parts of the UK. External mastic still waits for dry faces and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first. Coursehorn lies roughly 40 miles out from central London. Within reach of London, blocks run by agents and associations are common around stations; their frame mastic often ages block-wide.
Landlords with units on estates such as Hartley Dyke Business Centre (to the south-west of Coursehorn) can bring frame, door and external mastic across several units into one programme. Site managers at schools like Cranbrook School can fit frame mastic into the summer works. Trustees of buildings like Church of St Dunstan can bring frame and external mastic into a planned maintenance list.

FAQs: Coursehorn
Will you take on work at estates like Hartley Dyke Business Centre, close to Coursehorn?
Yes. Our area takes in Coursehorn and its surroundings, with estates and business parks such as Hartley Dyke Business Centre included. A few photos and the unit address let us price the work.
Is a smaller place like Coursehorn outside your area?
No. Small places get the same service as large ones. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
How soon can the area be used again?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
Do you supply RAMS and insurance details?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are CHAS accredited and a Constructionline member.
How do you handle work on occupied blocks?
Residents and tenants carry on as normal. We flag any areas that need internal access well before the dates so it can be arranged.
Does weather matter for sealant work?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
Keeping the joints sound
To get the most from the new sealant:
- Check sealant joints during planned building inspections
- Share your contractor requirements early
- Avoid piecemeal callouts where you can
- Ask residents or tenants to report leaks and draughts early
Our workmanship is covered for 12 months, so report any failure in that time. Beyond that, routine checks spot the next round of repairs.
One failed perimeter typically means others on the same building are close, so it pays to look at the whole elevation. Doing them together saves going back again and again.
From enquiry to sign-off
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. Rural sites near Coursehorn may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.
