Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Common problems we fix in Monk Street
Frames, panels and masonry expand and contract through the year, and every joint has to stretch and squeeze with them. If the joint or the product wasn’t suited to the movement, it splits long before it should.
Look out for the following:
- Patchy repairs in mismatched sealant
- Communal area joints that look neglected
- Estate-wide sealant that is simply worn out
- Brittle perimeter mastic across a building
For owners of several units at places like Williams Field Business Centre (3 miles south-west of Monk Street), one programme can deal with frame and external mastic across the lot.

Mastic sealing for commercial buildings in Monk Street
We diagnose before we prescribe: what has failed, what caused it and whether new sealant will actually solve it. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in, with backing rod setting the depth where it’s needed. Most enquiries involve complaints coming in block by block and occupiers reporting cold air round windows, across external wall and movement joints, shopfronts below residential blocks and communal kitchens and washrooms. Whether you call it commercial sealant work, mastic application or joint sealing, in Monk Street it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Around smaller places like Monk Street, older walls fitted with newer windows are a familiar sight. Perimeter mastic there has to grip an uneven face and suit the building’s character.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Site staff or a sealant specialist?
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.

Advice
Owners, agents and contractors
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
Building owners and managing agents use us on everything from one building to a spread of sites. One quote can cover more than one site, so there’s one set of paperwork to deal with.
Looking after buildings in and around Monk Street
Monk Street is about 35 miles from central London. Managed blocks of flats are a big part of commuter-belt property. The South East is one of the drier parts of the UK. External mastic still waits for dry faces and the right temperature, and the sunniest, most exposed sides of a building usually need attention first.
Buildings close to stations like Stansted Airport station (to the south-west of Monk Street) are often flats over shops, with frame mastic to keep sound. Older buildings near Monk Street, from historic houses such as Horham Hall, 1.5 miles to the west of Monk Street, to more modest stock, need compatible products when frames are resealed.

What sealant work can’t fix
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Glazing that needs replacing
- Asbestos-containing sealant, which we don’t remove
If in doubt, call the office on 01277 525 020 or send details through our quote form and we will say what we think.
Surfaces we seal
- Communal kitchens and washrooms
- Communal entrances and stairwells
- Window and door perimeters on blocks
- Shopfronts below residential blocks
- Balcony and threshold joints
- External wall and movement joints
What happens if it’s left?
Dealing with failed joints one report at a time is slow and scattered. A planned programme treats each building once, under a single quote and a single programme. Converted and older buildings near places like Monk Street tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
Why us?
- One phone line for London, the South East and Scotland
- Colours confirmed for the specified product
- Fully insured

Common questions from Monk Street clients
Is Monk Street too small for you to travel to?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Can you work at a site such as Williams Field Business Centre, by Monk Street?
Yes. Estates, retail parks and business parks around Monk Street, Williams Field Business Centre among them, are all within reach. A few photographs and the unit address let us price the work.
Will residents or tenants be disturbed?
Residents and tenants carry on as normal. We flag any areas that need internal access well before the dates so it can be arranged.
Will you quote for a small job?
Small jobs are welcome alongside larger packages. Send details for a fixed quote.
How long does a job like this take?
It depends on the scope, though a typical visit normally takes a few days for most blocks, with larger programmes scheduled building by building. For bigger or phased jobs, we’ll set out a timescale with the quote.
How much does the work cost?
That depends on the job: quantities, access, the product and any phasing. Call for a quote.
Does weather matter for sealant work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
