Leave it or put it right?
Patching the worst rooms as complaints come in is hard to manage. A planned programme deals with every room in order, with less disruption and one clear quote. Where a wall is exposed, as many are in small places like Foster Street, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we will go through it with you.
Why choose Mr Mastic in Foster Street

Commercial sealant in Foster Street, done properly
Landlords and agents with several properties can have bathrooms and kitchens resealed between tenancies. Several addresses can be quoted together to keep things simple. We work on hotel bathrooms, student & care accommodation and office washrooms & kitchens, and common reasons people get in touch are black, stained silicone in guest bathrooms and tired sealant ahead of a health and safety audit.
For a small place like Foster Street, the journey and timings are agreed in advance, so the job can fit around bookings, guests or opening times where possible.
Each job carries a 12-month guarantee.

Honest limits
We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:
- Failed tanking or loose tiles behind the sealant
- Fire risk assessments or certification
- Water coming from plumbing rather than sealant
If in doubt, phone 0345 464 0079 or email us and we will say what we think.
What we seal
- Welfare facilities
- Retail & leisure sites
- Student & care accommodation
- Office washrooms & kitchens
- Rental portfolios
- Hotel bathrooms
Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Give housekeeping the cure time for every room
- Add sealant to your planned maintenance checks
- Use mild cleaners on sealant, not bleach or abrasives
- Act on lifting sealant before it leaks
Extract fans need to work. Where a room has no window, the fan is what dries it out, and that’s what keeps mould away.
Black sealant in a staff washroom or guest bathroom draws complaints. Left long enough, it spreads through the bead, and only replacement fixes it.
How the visit works
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The work itself takes a few hours per area, with larger sites planned over several visits, including the tidy-up. In a small place like Foster Street, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- The first visit is a look round the site to agree the scope.
- Working hours are agreed, including early starts or out-of-hours work where it can be arranged.
- Each area is protected and stripped of old sealant.
- Once dry, every joint is resealed and tooled.
- Housekeeping or site staff are told when each area can be used.
Getting ready for the visit
- Tell us about any previous sealing or DIY attempts
- Let us know about stairs, lifts or work at height
- Mention any parking rules near the property

Advice
What the job involves on each surface
Retail & leisure sites
Customer washrooms are part of the impression a business makes, and clean, neat sealant makes them look cared for.
Office washrooms & kitchens
Office washrooms and tea points are used all day, so we can work early or out of hours where that can be arranged. We reseal around basins, urinals, worktops and sinks.
Commercial sealant around Foster Street
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in. Foster Street is part of Harlow, one of the post-war new towns. Like the other new towns, Harlow was planned with its own areas for industry and business, so workplaces sit close to the homes. Each has washrooms, kitchens and fire-rated joints to keep in order.
For site and facilities teams at buildings such as Henry Moore Primary School, busy washrooms and kitchens can be resealed in phases so they stay open. If you look after a church, hall or community building such as Church of All Saints, its kitchen and washroom sealant needs looking after like anywhere else. Rented homes near Harlow Mill station change hands often, and sealant work can be quoted for a single flat or a whole portfolio.
Foster Street is about 2 miles east of Harlow, in Essex. Across the CM17 area, we can carry out commercial sealant at your property. Foster Street is one of 644 towns and villages in Essex we cover. Our Chelmsford page covers work nearby (14 miles or so).
All of CM17 is covered for commercial sealant, from the main roads to the quietest streets. Whether your property is on Foster Street, Highfield Close and Hastingwood Park or a nearby road, we can help. We also cover Hastingwood (1 mile south), Newhall (1 mile north-west), Latton (1 mile west), Magdalen Laver (1 mile east) and Housham Tye (2 miles north-east). We also work in nearby towns such as Chelmsford (14 miles east), Brentwood (11 miles south-east), Billericay (15 miles south-east), Loughton (9 miles south-west), Waltham Abbey (8 miles south-west) and Great Dunmow (12 miles north-east).
Around Foster Street
In Foster Street, that means homes and buildings near John Barleycorn Public House, Passmores Academy and Brays Grove. The closest station to Foster Street is Harlow Mill station, roughly 2.3 miles north-west of the centre. A little further out are Princess Alexandra Hospital (3 miles west) and Harlow Mill (2.4 miles north-west). Green spaces nearby include Gernon Bushes.
DIY versus a professional finish
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Some sealant jobs are within reach of a careful DIYer, 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.
For landlords and businesses
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
