Commercial sealant contractors across RM7: what to expect
Mastic Doctor has been sealing joints for businesses and contractors since 2005, and the documents buyers ask for are ready: CHAS accredited, Constructionline member, five million pounds of public liability insurance and CSCS-carded applicators. Let us know which site documents you need and they’ll be confirmed with the quote. Most enquiries involve gaps behind commercial kitchen worktops and sinks and untidy joints in a reception, shop floor or lobby, across washrooms and tea points, floor and threshold joints and external facade joints.
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 begin with whatever information you have, whether that’s photographs, a drawing or a list of locations.
- We work out why the joints have failed and fix a quote for the agreed scope.
- We plan around your site hours and access windows, phasing the work where areas have to stay in use.
- We strip the failed bead and prepare both faces of the joint.
- The depth is set, primer is used where the maker calls for it, and the fresh bead is applied and tooled.
- Each area is inspected, signed off and backed by our 12-month guarantee.
What you’ll pay
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote and we’ll explain how it’s made up.

Shops, offices and hotels in RM7
Commercial buildings across RM7 range from older premises altered many times to recent units on business parks. Surfaces decide the sealant, from masonry to powder-coated frames and shop-fit panels.
We work across Greater London and the South East counties, and every job in RM7 starts with access, parking and site rules.
Rush Green: Refits at hotels like Mawney Hotel, 0.9 miles to the north of Rush Green, bring joints at vanity tops, bars and reception desks that guests see every day. With Rush Green inside the ULEZ and kerb space scarce, we sort access and loading before the first day on site.
What sealant work can’t fix
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- A failed roof covering or waterproofing membrane
- Misted, cracked or failed glazing units (a glazier’s job)
- A dripping trap, valve or pipe behind a fitting
Site staff or a sealant specialist?
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
For managing agents and facilities managers
Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.
If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.
What we are called out for in RM7
External sealant takes a steady beating from the weather. Sunny elevations dry the surface out and exposed ones take driving rain; in time the surface chalks, hardens and cracks. A hardened bead can’t follow the building any more.
If one of these sounds familiar, it’s time for a closer look:
- Expansion joints with the sealant torn out
- Smeared sealant across finishes from a rushed job
- Window and door perimeter joints that have cracked open
- Water staining near frames, panels or ceilings
Why act early?
A cheaper quote sometimes means the old bead stays in. New sealant laid on old silicone has nothing to bond to, so it peels. Every quote we give includes full removal and preparation, which is where the lasting value is.
Comparing quotes
- Can the work be phased to keep areas open?
- Which product they’ll use, and why it suits the joint
- What level of public liability insurance do they hold?
- Will CSCS-carded applicators be on site?
Questions about RM7
When can the area be used after sealing?
Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Do your applicators hold CSCS cards?
Yes. Our applicators hold CSCS cards.
What about asbestos in old mastic?
In buildings from before 2000 in particular, some old mastics and sealants may contain asbestos. Before cutting anything out, we ask for the asbestos register or survey, and if something is suspected, work stops until it’s tested.
Can you take on work for an FM or managing agent?
Yes. A large share of our work comes through facilities managers, managing agents and landlords, alongside main contractors. We can work to your instruction process and site rules.
How is commercial sealant work priced?
Start with whatever information is to hand. We follow up with questions or a visit where needed.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
