DIY versus a professional finish
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

Workplaces and buildings in Becontree
Commercial buildings in London often have strict access rules and limited loading, so out-of-hours working can be arranged where needed. London has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Letting a property close to Chadwell Heath station? Then several rental properties can be resealed on one programme. For site and facilities teams at buildings such as St Joseph's Catholic Primary School, busy washrooms and kitchens can be resealed in phases so they stay open.

What else we do in Becontree
What affects the cost of commercial sealant
Jobs vary more than people expect. The main factors:
- The old material and how stubborn it is
- The number and length of the joints
- Working hours on commercial sites
- How easy the joints are to reach
Doing several joints on one visit usually makes better use of the time than several visits. We’ll give you a clear price for the lot.
What to tell us for a quote
You do not need to know the technical terms. Just tell us:
- Whether it’s a home or a business
- A few photos by email, if you can
- Whether it has been sealed before
- The problem you’ve noticed
Need a quote? Please phone 0345 464 0079 or send us an email and tell us about the job. You will know what we plan to do, and what it will cost, before any work begins.
What we can’t put right
We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:
- Cracked trays or baths rather than failed joints
- Fire risk assessments or certification
- Extraction that is not working, which needs an electrician or ventilation contractor
If you are not sure, just call 0345 464 0079 or email us and we will give you a straight answer.
Surfaces we seal
- Welfare facilities
- Office washrooms & kitchens
- Student & care accommodation
- Rental portfolios
- Retail & leisure sites
- Hotel bathrooms
Do you need commercial sealant in Becontree?
Plenty of commercial bathrooms have no window at all, and where extraction is poor, damp hangs around. Mould then takes hold in the silicone.
Keep an eye out for these signs:
- Repeated reseals that don’t last
- Mouldy bathrooms flagged at a tenancy check
- Failed joints in office kitchens and tea points
- Washroom sealant that looks dirty however often it’s cleaned
For buildings such as St George's, any kitchen and washrooms need the same sealant care as any other building.
Questions to ask before you book
- Whether you can choose the colour
- What the cure time is
- Which sealant they’ll use, and why
- The length of the guarantee
Questions from Becontree
Is parking a problem for a job in Becontree?
Parking in Becontree, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.
Can you do commercial sealant in Becontree?
Yes, Becontree is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or send us an email and let us know what needs doing.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Which products do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
Can new sealant go over the old?
No. We remove every bit of old sealant first, so the new sealant bonds properly.
Are you ARBOMaster approved?
Yes. We are approved under the ARBOMaster scheme.
Can you take on a whole building?
Yes. After a site walk, we agree the scope and sequence, and you get one clear quote.
Landlord and commercial work in Becontree
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
If you manage several properties in or around Becontree, several properties can go on one quote. Just tell us the addresses and what each one needs, and photos by email help.
Why deal with it now?
Guests and staff judge a building by its bathrooms. Black sealant makes a clean room look dirty, and cleaning rarely puts it right. Replacing it does. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Becontree, the repair is bigger than the sealant job would have been.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are not sure whether it needs doing, call 0345 464 0079 or email us for an honest opinion and a quote.
Why us?
- Domestic, commercial and hotel work
- Anti-fungal sanitary silicone in wet areas
- More than 20 years in sealant work
- A sealant colour to suit the surroundings

The process
Once we are on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a morning for a small washroom, and a planned programme for bigger sites. In Becontree, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- We walk the site with you and agree the rooms, the order and the hours.
- Each area is protected and the old sealant cut out completely.
- We clean the joints, treat any mould and let them dry.
- New sealant suited to each area is applied and tooled.
- We check every room and give its cure time for housekeeping.
Getting ready for the visit
- Plan for the work area to be out of bounds to pets and children
- Tell us if parking is tricky
- On commercial sites, let us know about site rules
