Your questions answered
Is Nowhurst Business Park, near Rowhook, within your area?
Yes. Our area takes in Rowhook and its surroundings, with estates and business parks such as Nowhurst Business Park included. A few photographs and the unit address let us price the work.
Would you work within a site like Horsham Hospital?
Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.
Is Rowhook in your area?
Yes. We take on work across Rowhook, and the same phone number covers every area.
Is any job too small?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
Do you use the sealant named in the specification?
The specification decides the product, and we’ll raise it if something in it doesn’t suit the joint. Specifications often reference BS EN 15651 or BS 6213.
Can you quote from photos?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.
Do you have public liability insurance?
Yes. Our insurance certificate can be sent alongside the quote.
About our construction mastic in Rowhook
Buyers, tenants and clients notice sealant lines long before they notice the structure. Untidy or missed joints are among the commonest snag items, and every return visit costs time. We seal so the snag list stays short, whatever the size of the scheme. We work on floor and skirting junctions, window and door perimeters and internal decorators’ caulk, and what we are called in for most is internal caulk splitting as the building dries out and old sealant on a refurbishment that needs stripping before new work. Facilities teams, main contractors and managing agents in Rowhook tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Conversions of older rural buildings near smaller places such as Rowhook bring stone, flint, brick and timber up against new glazing. A product that grips an irregular face, with a colour that suits the building’s character, is normally what’s needed.
Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

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 and we install what’s specified.
Internal decorators’ caulk
Caulking is often done in a hurry by whoever’s on site. Done properly, it saves decorators time and gives a clean line.
Our process
Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. For a building around Rowhook, tell us how to find it and who will meet us. 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.
- We agree with the site team which areas come first.
- Plots or floors are sealed as they’re handed over.
- Every joint is cleaned, set to depth and sealed with the specified product.
- Snags are cleared and the package signed off with our 12-month guarantee.
Preparing the site
- Tell us your opening times and when work is allowed
- Point out parking and an unloading spot
- Let building users know which areas are affected
Getting a fixed quote
Send us photos, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.

Maintenance after handover
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:
- Put any product change through the designer first
- Bring the mastic contractor in after the last trades are through
- Note which sealant went where at handover
- Ask cleaners to use soft cloths around fresh sealant
At handover, keep the product details with the O&M information. That helps the building owner maintain the joints later, and tells you what to reseal with. Tell us what records you need and we’ll confirm with the quote.
One unsealed frame can let water into finished internal areas. On a new building that means remedial work after decorating. A check of every frame before decorators start is worth the time.
What we are called out for in Rowhook
Most mastic snags on new buildings come from sequencing rather than product. Sealing before decorators, flooring or other trades have finished leaves joints exposed to damage, so they end up back on the snag list.
Typical triggers for a call:
- Frame perimeters left unsealed or poorly sealed
- External joints sealed in damp or cold conditions that are now failing
- A mastic package split between trades with no clear owner
- Bath and shower joints scraped during the final clean
Hospital estates such as Horsham Hospital, 3.7 miles south-east of Rowhook, tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.

What affects the price in Rowhook
We price every job individually. The main factors are:
- Any access equipment needed
- Site requirements such as inductions and permits
- Location, for remote and island sites
- Joint width, depth and condition
The specified product makes a difference, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.
Sending details for a quote
A few photographs plus some basic facts will normally do. Please tell us:
- Asbestos survey details if the building is older
- Any specification or named product
- Clear photographs of the problem areas
- Access details, including height
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, speak to us on 01277 525 020 or email a schedule or drawings.
Construction mastic around Rowhook: points for this area
At about 31 miles from central London, Rowhook is within reach of the capital. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, so mastic packages have to keep pace with busy programmes. Rowhook 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.
School extensions, at buildings such as Farlington School, typically run to the summer holidays, mastic included. For contractors refurbishing units at places like Nowhurst Business Park, which lies south-east of Rowhook, the mastic covers cladding panels, roller-door and window perimeters.

What sealant work can’t fix
Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is one of these:
- Rework caused by others damaging completed areas
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Deciding which fire-stopping product a penetration needs
Not sure which it is? You can give us a call on 01277 525 020 or send photos by email and we will tell you honestly before you book.
