About our construction mastic in North Heath
External mastic depends on the weather in a way most internal trades don’t. Cold or damp mornings, frost and condensation on frames can all hold external sealing up. Internal sealing often fills those days. If you have missed perimeter joints on a new elevation and sanitary sealant damaged by following trades, we can put it right, whatever the surface. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in North Heath, preparation and product choice get the time they need.
In the countryside around places like North Heath, conversion schemes put new frames into old stone, flint, brick or timber. A product that grips an irregular face, with a colour that suits the building’s character, is typically what’s needed.
Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

Construction mastic in North Heath: the local picture
The South East is one of the drier parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so the external programme keeps a little slack. North Heath is about 39 miles from central London. Towns within reach of London tend to keep building, from flats to offices and schools, which keeps mastic packages in demand.
When a college such as Brinsbury College, 0.6 miles north of North Heath, builds or refurbishes, the mastic package normally has to fit around students and staff. Recladding or extending a unit at a site like Broomers Hill Business Park, 0.8 miles south-west of North Heath, brings panel joints and frame perimeters into the programme.
North Heath is about 9 miles south-west of Horsham, in West Sussex. We cover commercial sites throughout North Heath, whether it’s a single job or part of a planned programme. North Heath is one of 373 places we cover in West Sussex for mastic packages. Sites around Brighton have their own page, roughly 18 miles from North Heath.

What sealant work can’t fix
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Frames fitted out of tolerance
- Designing joint widths or choosing the specification (that sits with the designer)
- Glazing units that are cracked or misted
If in doubt, call 01277 525 020 or send photos by email and we will say what we think before you book.
Surfaces we seal
- Sanitary and kitchen joints
- Internal decorators’ caulk
- Brick and block movement joints
- Window and door perimeters
- Floor and skirting junctions
- Cladding and panel joints

Questions about North Heath
Do you cover business parks and estates near North Heath, such as Broomers Hill Business Park?
Yes, sites like Broomers Hill Business Park are within our area, along with the rest of North Heath. Photos and a short description are enough for a first look.
Is North Heath off your patch?
Not at all. North Heath 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.
Can one quote cover more than one building?
Yes. Several buildings can share a single quote, with one point of contact across South East England, Greater London and Scotland.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
How long do sealant joints last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
Is colour matching possible?
It depends on the product specified. Some ranges are wide, others limited, so the available colours are confirmed with the quote.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
When to call us in North Heath
Swapping the specified sealant for a cheaper general-purpose product is a common cause of failure. A sealant that isn’t right for the substrate or the movement will fail ahead of time. We stick to the specified product, or put any alternative to you first.
Things that typically lead to an enquiry:
- Early adhesion failures on new external joints
- A long mastic snag list close to completion
- Bath and shower joints scraped during the final clean
- Missed perimeter joints on a new elevation
With historic properties like Old Place Manor (to the south-west of North Heath) in the area, refurbishment work often meets old masonry that needs compatible sealants.
What your quote should include
- Will RAMS and insurance details be available?
- Whether their applicators hold CSCS cards
- Proof of insurance

General trades versus a specialist
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
What sets the cost
There’s no standard rate for sealant work, since sites vary so much. What we look at:
- Induction, permit and paperwork requirements
- How accessible the joints are
- How much existing material needs removing
- Backing rod, priming and other preparation
Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
Details that help us quote
There’s no need for a formal survey. These details are enough to start:
- What the building is and how it’s used
- The postcode of the building
- Any dates the work must fit around
- Any specification or named product
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, ring 01277 525 020 or send details through our quote form.
From enquiry to sign-off
In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then handed back before the next one starts. Jobs in and around smaller places like North Heath are usually planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.
- We walk the site or review drawings to understand the package.
- You receive a fixed quote covering scope, products and sequence.
- Site paperwork is confirmed and our CSCS-carded applicators are inducted.
- We seal plot by plot or floor by floor in line with the programme.
- Problems we find, such as oversized gaps, are raised right away.
- The package is closed out, snags cleared and backed by our 12-month guarantee.
Before we start on site
- Agree which areas must stay open
- Make sure the joints can be reached
- Flag any permit to work we’ll need
