How we handle commercial sealant contractors in Foster Street
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. Let us know which site documents you need and they’ll be confirmed with the quote. The enquiries we see most involve greasy, split joints in a kitchen or tea point and damp patches where an external joint has failed, across washrooms and tea points, external facade joints and kitchen worktops and splashbacks. A specialist sealant contractor works differently from a general builder: in Foster Street, that means joint design, primers and backing rod as standard.
The most common commercial job in Foster Street is resealing joints that have simply reached the end of their life: hardened, cracked or shrunk away from the faces, and letting water or dirt in.
A job in a smaller place like Foster Street is usually a single building. We plan the visit so everything on the list is done in one go, with the right products and colours on hand.
Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

What we can’t put right
Honesty saves time and money. New sealant won’t cure:
- Leaks from pipework, wastes or valves (that’s plumbing)
- Leaking roofs, gutters or flat-roof membranes (those need a roofer)
- Broken glass or blown double-glazed units
If you are not sure, just ring 01277 525 020 or use the quote form and we will give you a straight answer before you book.

What else we do in Foster Street
Maintenance after handover
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Ask cleaners to use a soft cloth and mild cleaner on sealant
- Make sure ventilation in wet areas is switched on and working
- Check the asbestos register before anyone disturbs old sealant in an older building
- Keep barriers up until the new sealant has cured
Brief your cleaning team on the joints that have been resealed. Abrasive pads, scrapers and some strong chemicals damage sealant surfaces.
Movement joints that fill with debris stop working. With nothing soft to close against, the materials either side take the load and start to break up. That turns a sealant job into something bigger.
On site: what to expect
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. If others near Foster Street need work, visits can be combined. You’ll have a fixed quote before work starts.
- Send details through our quote form, or ask for a site visit.
- The cause is diagnosed and the scope priced as a fixed quote.
- Work is phased around your occupiers where areas need to stay in use.
- Old sealant is cut out completely, never sealed over.
- Each joint gets a suitable sealant, laid to depth and tooled.
- We check the work with you, and the 12-month guarantee starts.
Getting the site ready
- Tell staff and tenants when we will be in
- Send asbestos survey details if the building is pre-2000
- Share your working hours and any access restrictions

Advice
Common questions from Foster Street clients
Do hotels near Foster Street have to close for sealant work?
In the majority of cases no closure is needed: we work room by room or floor by floor. Housekeeping and our team agree each day’s rooms.
Is Foster Street too far out for you?
Not at all. Foster Street is within our area. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
Does the weather affect the work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
How many days will you need on site?
The duration is planned around your programme and the access we’re given. You’ll have an expected duration with the quote.
Are your applicators CSCS-carded?
Yes. Our applicators hold CSCS cards, as many construction sites ask for.
Is failed sealant stripped out, or sealed over?
The old bead is stripped out first. Then the joint is cleaned, primed where the maker specifies, backed to depth and resealed.
How do we get a quote?
Send photographs, drawings or a list of locations. Where we need to see it, we’ll arrange a site visit, then send a fixed quote.
Why it’s worth doing now in Foster Street
Spot repairs have their place. Where the remaining sealant is just as old, it tends to fail soon after, and a second visit means paying for access and set-up again. Where it helps, we quote a patch and a full reseal side by side. For buildings around smaller places like Foster Street, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.
We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote.

Common problems we fix in Foster Street
Washrooms and kitchens wear sealant out in their own way. Damp, harsh cleaning products and poor ventilation let mould take hold inside the bead, and once established it rarely cleans out. Replacement with a sanitary anti-mould silicone is the lasting answer.
Clients normally get in touch after noticing one or more of the following:
- Mouldy silicone around WCs, urinals and vanity tops
- Frame mastic that has hardened and come away from the wall
- Layers of sealant, all of them failing
- Leaks that seem to come through a sealant line
Offices and shops close to stations such as Harlow Mill station (to the north-west of Foster Street) tend to be busy all day, so sealant work is planned around opening hours.
Questions to ask before you book
- How joint depth will be controlled
- How the existing material will be dealt with
- What site paperwork they can supply
- Whether their applicators hold CSCS cards

Shops, offices and hotels in and around Foster Street
Less than 3 miles from Foster Street there are at least three named estates and business parks. Units on sites like these change tenants and get refitted, and each refit leaves joints to seal. Rainfall across the South East, Foster Street included, is lower than in many parts of the UK. Even so, outside sealing waits for a dry joint, and cold, damp mornings can delay it.
For a hotel such as Park Inn Hotel, which lies west of Foster Street, the colour of a joint at the bar or the bath matters to the look of the room. A business with units at Hastingwood Business Centre and Harlow Innovation Park needn’t use two contractors for its sealant.
