What sets the cost
Each job is priced on its own details. The main factors are:
- The site’s rules and procedures
- How much existing material needs removing
- Joint width, depth and condition
- The product specified
We don’t publish prices, since every building and every scope is different. Call for a quote.
Sending details for a quote
Good information means a firmer quote. When you get in touch, include:
- Whether the building will be occupied during the work
- Asbestos survey details if the building is older
- The product your specification calls for
- The site address and postcode
Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.
Facade sealing for commercial buildings in Copthorne
Access is part of every facade job, and we plan it with you before quoting. Let us know what access exists or is planned, and any site rules we need to work around. We work on shopfront frames, window and door perimeters and coping and flashing joints, and the failures we are asked to look at most are water coming in around window frames and weathered joints at frame-to-structure perimeters. Facilities teams, main contractors and managing agents in Copthorne tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Around places like Copthorne, a lot of construction is the conversion of older buildings, which leaves joints between old walls and new frames that need a sealant able to take the movement.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

What the job involves on each surface
Render and coated surfaces
Where the joint will be painted over, a paintable hybrid or PU sealant may suit. We confirm the product with you before starting.
Perimeter joints at frames and structure
Where framed systems such as shopfronts meet the building structure, there is a perimeter joint to seal. We seal those perimeter joints.
Sites and facades in and around Copthorne
At about 25 miles from central London, Copthorne is within reach of the capital. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and main contractors there need mastic that keeps to the programme. The area within 2 miles of Copthorne holds plenty of hotels. When hotels extend or refit, the work is usually squeezed between peak periods, mastic included.
Hotel extensions and refits, at places such as Copthorne Hotel Gatwick, which lies south of Copthorne, normally run between busy periods, so the sealing is squeezed into short windows. When units on a site such as Kiln Heath Farm Business Centre, 0.8 miles north of Copthorne, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. Extensions at sites like Langley Green Hospital (psychiatric), 2.7 miles west of Copthorne, usually sit beside working departments, and the mastic follows strict access rules.
Copthorne is about 3 miles north-east of Crawley, in West Sussex. Looking for facade sealing in Copthorne? We can help. Copthorne is one of 373 places in West Sussex on our list for facade joints. For work in that direction, see our Brighton page, about 21 miles away.

Questions we are asked in Copthorne
Can work at a site such as Crawley College fit around teaching?
Yes. Education sites usually want the work in vacations or in phases during term, and we plan to suit. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Is a smaller place like Copthorne outside your area?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Does the weather affect the work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
Do you hold CHAS accreditation?
Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
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 joint cleaned back to sound material. That is what makes the new joint last.
Is colour matching possible?
That depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
For managing agents and facilities managers
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
We work for building owners and managing agents on everything from one building to a spread of sites around Copthorne. One quote can cover more than one site, which keeps the paperwork simple.
From enquiry to sign-off
Where the site stays busy, 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 we move to the next. Several jobs near Copthorne can be grouped on one trip. Tell us your site hours and we will plan around them.
- Photos, drawings or a visit tell us about the joints and the access.
- We confirm the joint type, movement and the specified product.
- The existing bead comes out in full.
- Primer is applied where the maker specifies it.
- Rod goes in to fix the depth, then the joint is sealed and tooled.
- The finished joints are checked with you.
Preparing the site
- Tell us which areas need to stay in use
- Arrange parking or a loading space
- Tell us your opening times and when work is allowed
Request a quote
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.
Advice
Leave it or put it right?
Patch repairs over old sealant tend to come back. A full cut-out and reseal costs more on the day but lasts much longer, so you aren’t paying for the same joint twice. Over time, UV, weather and movement wear any sealant out. Replacing it before it fails keeps water out.
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.
