Your questions answered
Can you work at a site such as Colhook Industrial Park., by Northchapel?
Yes. We cover Northchapel and the area around it, including industrial estates, business parks and retail parks such as Colhook Industrial Park.. To start, just call the office on 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.
Is Northchapel too small for you to travel to?
No. Places such as Northchapel are covered as much as the big towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
Is it okay to overlay old mastic?
No. New sealant won’t hold on old sealant, so the old bead is cut away and the faces are cleaned before resealing. That is what makes the new joint last.
Do you seal on top of existing sealant?
No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
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.
Does weather matter for sealant work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
Can staff carry on working while you are here?
Normally, yes. Phased work can be planned so areas stay in use.
Facade sealing for commercial buildings in Northchapel
Water ingress at window frames is a frequent reason facilities managers contact us. Failed perimeter sealant is a frequent cause, though that isn’t the only cause. We will tell you if we think the leak is coming from somewhere sealant won’t fix. Most enquiries involve water coming in around window frames and gaps between rainscreen or cladding panels, across coping and flashing joints, perimeter joints where frames meet the structure and shopfront frames. A specialist sealant contractor works differently from a general builder: on jobs in Northchapel, preparation and product choice get the time they need.
In the countryside around places like Northchapel, 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.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

When something else is needed
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Damp caused by condensation inside the building
- Specialist high-level access methods
- Joints whose design needs changing by the specifier

New build and refits around Northchapel
At about 39 miles from central London, Northchapel is within reach of the capital. Construction around the commuter belt mixes station-side flats with refurbished offices and units, so mastic packages have to keep pace with busy programmes. The South East is one of the drier parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so external mastic is timed for workable conditions and agreed with the site manager.
Recladding or extending a unit at a site like Colhook Industrial Park. (to the south of Northchapel) brings panel joints and frame perimeters into the programme. Extensions at sites like Haslemere and District Hospital, 3.7 miles north-west of Northchapel, normally sit beside working departments, and the mastic follows strict access rules.

Surface by surface
Coping and flashing joints
Coping and flashing joints are included where sealant is the specified fix. They sit in the most exposed positions on the building and need a durable external sealant.
Window and door perimeters
Perimeter joints move as frames expand and contract in the sun. Rod placed at the right depth lets the bead stretch without tearing.

For managing agents and facilities managers
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.
If you look after buildings for someone else, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end.
Why it’s worth doing now in Northchapel
A few metres of new sealant compare well with replacing ceilings, linings or damaged stock. Leaks travel along the structure, often turning up far from the joint. One visit to deal with every failing joint makes more sense than several trips to a place like Northchapel. Send photos of each area and we’ll quote for the lot.
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 and we will price your job on its own details.
