Commercial sealant contractors for businesses in Rowhook
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
When something else is needed
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Cracking that needs a structural engineer to look at it
- Misted, cracked or failed glazing units (a glazier’s job)
- Roof leaks that only look like a joint problem
If in doubt, phone 01277 525 020 or email a schedule or drawings and we’ll say what we think.
Where we work in Rowhook
- Kitchen worktops and splashbacks
- Floor and threshold joints
- Movement joints in walls and floors
- External facade joints
- Window and door perimeters
- Washrooms and tea points
Commercial mastic work in Rowhook
Mastic Doctor has been sealing joints for businesses and contractors since 2005, and the paperwork side is in order: we’re CHAS accredited and a Constructionline member, our applicators hold CSCS cards, and we carry five million pounds of public liability insurance. If your site needs RAMS, an insurance certificate or CSCS details, say so and we will confirm with the quote. If you are dealing with black mould through washroom sealant that won’t clean off and earlier reseals applied straight onto the failed bead, we can help, on external facade joints, washrooms and tea points and movement joints in walls and floors alike. One point of contact handles commercial sealant work in Rowhook from the first photographs to the final walk-round, for single jobs and planned programmes alike.
We price commercial jobs in Rowhook from photos, drawings or a site visit, and the scope is set out in writing.
Work in smaller places such as Rowhook tends to come one building at a time: a pub kitchen, a hall, a small office. We’ll want a full list and photographs first, so the right products come on the day and nothing waits for a second trip.

How the quote is worked out
Sealant work doesn’t have a standard rate, because every site is different. What we take into account:
- Induction, permit and paperwork requirements
- Whether old sealant has to be cut out first
- Backing rod, priming and other preparation
- Which sealant the job calls for
What a job costs comes down to the quantity of joints, how much old material needs removing and how the joints are reached. Call for a quote when you’re ready.
Before you send an enquiry
For an accurate fixed quote, we need a clear picture of the site. Send us:
- The product your specification calls for
- Your programme or deadline
- How the joints are reached, and at what height
- Whether an asbestos survey exists
Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, speak to us on 01277 525 020 or email us.
Shops, offices and hotels in and around Rowhook
Rowhook is about 31 miles from central London. The South East around the capital has large numbers of business parks, offices and retail centres, especially around the motorway corridors. Occupiers with several premises in the region tend to prefer one contractor and one point of contact. Rowhook has three care or nursing homes no more than 2 miles away. In care settings, a neat joint at a kitchen worktop or a lounge window is part of keeping the place easy to clean; colours can be chosen to suit the interior.
Units at places like Broadbridge Retail Park, 2.7 miles to the south-east of Rowhook, are refitted as brands change, and the joints have to suit each new scheme. On a business park such as Nowhurst Business Park (1.1 miles south-east of Rowhook), sealant work tends to follow fit-outs: receptions, tea points, washrooms and frame perimeters. A business with units at Nowhurst Business Park and Northlands Business Park needn’t use two contractors for its sealant.
Rowhook is about 4 miles north-west of Horsham, in West Sussex. We send applicators to Rowhook for sealant joints, handled exactly as we handle every other area. Our West Sussex coverage takes in 373 places, large and small. For work in that direction, see our Brighton page.
Postcode districts covered here: RH12. If your building is just outside Rowhook, we cover Warnham (2 miles east), Broadbridge Heath (2 miles south-east), Itchingfield (3 miles south), Tower Hill (4 miles south-east) and Holbrook (4 miles east). Further afield, our area takes in Crawley (9 miles east), Haywards Heath (15 miles south-east), Burgess Hill (15 miles south-east), Broadfield (8 miles east), Storrington (12 miles south) and Billingshurst (6 miles south-west).
Local landmarks in Rowhook
In Rowhook, that means premises near The Chequers Inn Public House and Farlington Strood Park. The nearest railway station is Warnham station, roughly 3 miles east. Nearby you’ll also find Horsham Hospital (3.7 miles south-east) and Christs Hospital School Museum (3.9 miles south-east). Not far away are Warnham LNR and Vann Lake.
Keeping the joints sound
To get the most from the new sealant:
- Deal with small splits before they become leaks
- Brief cleaning contractors to avoid scourers and blades on sealant
- Keep barriers up until the new sealant has cured
- Look at the sealant around anything that has been moved or replaced
Later works are the usual way new joints get damaged. When fittings are moved or cabling added, the sealant nearby is easily disturbed. If that happens, phone 01277 525 020 or email drawings and photos and we will price putting it right.
Once sealant fails in a movement joint, grit and debris get in. The joint can no longer close, so its edges crack or spall. That turns a sealant job into something bigger.
For managing agents and facilities managers
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.
Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, and our applicators hold CSCS cards.
Our process
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then handed back before we move to the next. Jobs in and around smaller places like Rowhook are normally planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.
- Site photographs, drawings or a visit tell us what’s there and how it has failed.
- A fixed quote follows, with removal and preparation included.
- Sequence, access and working times are settled before the first joint is touched.
- The failed sealant comes out and the faces are prepared, with primer where required.
- Depth is set with backing, then the sealant is applied, tooled and the area tidied.
- Completed areas are signed off with you under our 12-month guarantee.
Preparing the site
- Warn occupants and staff about the work
- Point out any areas we must not close
- Point out parking and an unloading spot
Ask for a quote

Common questions from Rowhook clients
Do you cover business parks and estates near Rowhook, such as Nowhurst Business Park?
Yes. Estates, retail parks and business parks around Rowhook, Nowhurst Business Park among them, are all within reach. A few photos and the unit address let us price the work.
Is a smaller place like Rowhook outside your area?
No. Small places get the same service as large ones. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
Are you CHAS accredited?
Yes. We are CHAS accredited and a Constructionline member.
Do you take on multi-site sealant work?
Yes, within the areas we cover: South East England, Greater London and Scotland. Each site gets the same process and a single contact.
Could the old sealant in an older building contain asbestos?
Some older mastics did contain asbestos. That’s why we ask for the asbestos information first, and stop if a material is suspect until it’s tested. HSE guidance on asbestos is a useful reference.
Do you work for facilities managers and managing agents?
Yes. You can send details through our quote form, and we will confirm any paperwork you need with the quote.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
When to bring in a specialist
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
