Commercial sealant contractors in RH19: how it works
On older buildings, particularly those put up before 2000, some old mastics and sealants may contain asbestos. Before anything is cut out, we ask for the asbestos register or survey, because the duty to manage asbestos sits with the dutyholder. Anything suspect is left alone until it has been tested (removing asbestos-containing materials isn’t something we do). We work on washrooms and tea points, floor and threshold joints and window and door perimeters, and what we’re called in for most is greasy, split joints in a kitchen or tea point and sanitary sealant that has gone black and patchy.
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish.
- We start with the evidence: photos, drawings or a look on site.
- A fixed quote follows, with removal and preparation included.
- Sequence, access and working times are settled before the first joint is touched.
- Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
- Depth is set with backing, then the sealant is applied, tooled and the area tidied.
- We hand back each area with its cure time and our 12-month guarantee.
What you’ll pay
Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Commercial premises across RH19
The commercial stock in RH19 mixes older town-centre buildings with newer offices and units, in places such as East Grinstead, Felbridge and Ashurst Wood and beyond. Surfaces decide the sealant, from masonry to powder-coated frames and shop-fit panels.
Around the motorway corridors of the South East, business parks and industrial estates are common, and RH19 is part of the area we cover.
East Grinstead: Offices at parks like Bulrushes Farm Business Park (0.9 miles south of East Grinstead) have receptions, kitchens and glazed partitions where a tidy joint matters. Offices and shops close to stations such as East Grinstead station (under half a mile west of East Grinstead) tend to be busy all day, so sealant work is planned around opening hours.
Looking after the joints
Keep the joints in good shape with a few simple steps:
- Keep abrasive pads and scrapers off resealed joints
- Respect the cure time before reopening an area
- Check the asbestos register before anyone disturbs old sealant in an older building
- Check joints after other trades have worked nearby
In washrooms and kitchens, extraction makes a real difference to sealant life. Extraction that isn’t working keeps the joints wet, which is how mould gets back in. Your maintenance team can look at extract fans at the same time.
Occupiers often notice failing sealant before the facilities team does, and it reflects on how the building is run. Planned replacement saves fielding the same complaint again and again.
When something else is needed
We check first that sealant really is the fix. It isn’t the answer for:
- A failed roof covering or waterproofing membrane
- A dripping trap, valve or pipe behind a fitting
- Cracking that needs a structural engineer to look at it
For managing agents and facilities managers
Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. RH19 can form part of a wider programme.
Whether you are a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.
Leave it or put it right?
Sealant is often treated as an afterthought by the trade that fitted the element. Choosing the product, setting the depth and preparing the faces are what a specialist brings, and they’re where most failures begin. It shows over the following seasons rather than at handover.

Common problems we fix in RH19
Plenty of failed joints were never sealed with the right product. Painters’ acrylic in a moving joint, vinegar-smelling silicone on metal or natural stone, or a high-modulus product where a low-modulus one was needed. BS 6213 gives guidance on choosing construction sealants.
Things that usually lead to an enquiry:
- Shrunken sealant along kitchen worktops and splashbacks
- Expansion joints with the sealant torn out
- Leaks that seem to come through a sealant line
- Mouldy silicone around WCs, urinals and vanity tops
FAQs: RH19
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
Can one contractor look after sealant on all our buildings?
Yes, across South East England, Greater London and all of Scotland. One contact and one process for every building makes a portfolio easier to manage.
What guarantee do you give on resealing?
The work is guaranteed for 12 months. Should a joint we sealed give trouble during those 12 months, let us know and we will look at it.
How long does a typical visit take?
The duration is planned around your programme and the access we’re given. You’ll have an expected duration with the quote.
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
Is it OK to apply fresh sealant over existing beads?
Every scrap of failed sealant is removed before the new bead goes on. A bead laid on old silicone peels away.
Do you cover RH19?
Yes. RH19 falls within our area, and the simplest way to start is to speak to us on 01277 525 020 or send details through our quote form.
