How we handle construction mastic in Capel
Site managers want applicators who turn up with the right cards and paperwork. We’re a Constructionline member and CHAS accredited, and every applicator holds a CSCS card, and we’re fully insured. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We work on window and door perimeters, cladding and panel joints and floor and skirting junctions, and the usual reasons a site gets in touch are a long mastic snag list close to completion and oversized or tapered gaps around new frames. A specialist sealant contractor works differently from a general builder: in Capel, that means joint design, primers and backing rod as standard.
Around smaller places like Capel, building work typically means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant.

Building owners, agents and FMs in Capel
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Capel can sit alongside others in a wider programme across Surrey.
Main contractors use us as their sealant subcontractor. We work to your programme, your specification and your site rules.
Our process
We schedule the visit to fit the site hours and access windows you give us. While we are working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. Rural sites near Capel may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.
- Drawings, specification and programme come to us.
- Quantities are measured and a fixed price returned.
- The sequence is agreed with the site manager.
- Each area is sealed when it’s released.
- Every joint is cleaned, set to depth and sealed with the specified product.
- After snagging, the work is handed over under our 12-month guarantee.
Preparing the site
- Tell us which areas need to stay in use
- Let us know about inductions and permits
- Make sure the joints can be reached
Ask for a quote
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to phone 01277 525 020 or email the details over with what you know.

When it isn’t the sealant
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Oversized gaps that need packing or adjustment by others
- Rework caused by others damaging completed areas
- Faulty frames rather than failed sealant
If in doubt, speak to us on 01277 525 020 or use the quote form and we will say what we think.
Joints and surfaces we work on
- Sanitary and kitchen joints
- Window and door perimeters
- Cladding and panel joints
- Internal decorators’ caulk
- Floor and skirting junctions
- Brick and block movement joints
General trades versus a specialist
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
Your questions answered
Do you take on work at healthcare sites like Horsham Hospital?
Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Is Capel too small for you to travel to?
No. Places such as Capel are covered as much as the big towns. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.
When can you be on site?
The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.
Do you use the sealant named in the specification?
Specification first, then the maker’s instructions. Primers, backing and joint depth follow what the manufacturer sets out.
How long does a typical visit take?
We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.
What if there’s asbestos in the old mastic?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.
Do you need to see the site first?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.
Different surfaces, different methods
Fire-rated sealant where specified
Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the manufacturer’s tested detail. Fire stopping design belongs to the designer and building control.
Window and door perimeters
Gaps around frames have to be within the sealant’s range. Gaps outside the product’s range are raised with the site team before sealing starts.

What else we do in Capel
New build and refits around Capel
Capel sits in one of the drier corners of the country, the South East. Winter mornings still bring frost and condensation on frames and panels, which is why external dates are agreed with the site manager. At about 26 miles from central London, Capel is within reach of the capital. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and each scheme needs its mastic sealed to programme.
New wings at hospitals like Horsham Hospital (5.6 miles south of Capel) bring long runs of window and panel joints to seal. For contractors at a school such as Scott Broadwood CofE Infant School, sealing has to be finished before term starts.

Aftercare for building managers
Your facilities or cleaning team can help the joints last. Share these points with them:
- Bring the mastic contractor in after the last trades are through
- Brief the final clean team to avoid blades near sealant
- Share drawings and the specification as soon as possible
- Flag uneven or tapered frame gaps early
Tell the builders’ clean team which areas have new sealant. Scrapers used on frames and worktops can nick or lift a new bead, so stick to soft cloths and gentle cleaners near sealant.
In wet areas, a weak sanitary joint shows up quickly once the building is occupied. Water gets behind trays, vanity tops and panels, and the repair falls into the defects period. Getting the product and preparation right first time avoids that.
