Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Mastic sealing in South Street, done properly

Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. A planned, building-by-building programme often works better than reacting to each complaint, with each block quoted and scheduled in turn. If you’re dealing with damp patches beside frames and no planned programme for sealant, we can put it right, whatever the surface. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in South Street it comes down to the same thing: the right product in a properly prepared joint.

Owners and agents with buildings around smaller places such as South Street tend to manage small terraces of association properties, converted barns and commercial units. Mastic around frames and on external joints wears out in time, whatever the building.

Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Signs you need mastic sealing in South Street

Topping up old mastic is a common shortcut. New sealant won’t grip failed sealant, so these repairs rarely last.

Typical triggers for a call:

  • Draught complaints from residents or tenants
  • The same joint failures repeated across a portfolio
  • Damaged joints in communal entrances and corridors
  • Brittle perimeter mastic across a building

Schools and community buildings such as Boughton-under-Blean and Dunkirk Primary School need frame and external mastic kept sound like any building.

What your quote should include

  • How they handle RAMS and site documents
  • Their pre-qualification and accreditations
  • How joint depth will be controlled
  • Their public liability cover

How to choose a sealant contractor

Why it’s worth doing now in South Street

Reacting to every complaint means sending someone out block by block. Planned resealing covers a whole building or estate in one go and is simpler to manage and budget. Older rural buildings around South Street move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we will explain how it’s made up.

Why us?

  • Joints cleaned back to sound surfaces
  • Health and safety: CHAS accredited
  • Coloured sealants to suit the setting, where available
  • Fully insured, including public liability cover

Quoting for work in South Street

Your fixed quote is built from the real scope. It allows for:

  • Removal of failed or old sealant
  • Distance, for remote addresses
  • Which sealant the job calls for
  • Phasing around occupants

The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

What to include in your enquiry

The more we know, the firmer the quote. Helpful details to send:

  • Access details, including height
  • Specification clauses that apply
  • Approximate linear metres or a joint schedule
  • Photos of the joints, close up and from further back

For a fixed quote, phone 01277 525 020 or email the details over with the site address and an outline of the work. You can also send details through our quote form.

Questions about South Street

Can you quote for mastic across several buildings in and around South Street?

Yes, we quote for single buildings and for programmes across several blocks. Send the addresses and photos and we’ll give a fixed quote.

Is a smaller place like South Street outside your area?

No. Small places get the same service as large ones. We work across Greater London and the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

How long does a job like this take?

It depends on the scope, but the work normally takes a day or two for a single block, longer for an estate programme. For bigger or phased jobs, we’ll set out a timescale with the quote.

How long do sealant joints last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

What if the old mastic contains asbestos?

Some mastics in pre-2000 buildings contain asbestos. We check the asbestos register or survey before disturbing it, and if it’s suspected, work stops until it’s tested.

What about access for upper-floor joints?

Every block is different. How upper joints are reached is agreed before work is booked so the fixed quote reflects it.

Will residents or tenants be disturbed?

We plan around people living or working in the building. We agree the programme so you can notify occupiers, and entrances stay in use.

From enquiry to sign-off

Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. Smaller jobs around South Street can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work starts.

Advice

For owners and agents in South Street

Central London is about 47 miles from South Street. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres; their frame mastic often ages block-wide. South Street is in the South East, one of the UK’s drier regions. External mastic still waits for dry faces and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first.

Historic properties like Belmont House and Gardens (4.4 miles west of South Street) show the age of some local stock, where frame mastic must suit soft brick or stone. For agents with blocks near Selling station, less than half a mile to the south-west of South Street, a block-wide mastic programme deals with frames, balconies and entrances in one go.

South Street is about 3 miles south-east of Preston, in Kent. South Street sits inside our coverage and the rest of Kent, with the same fixed quotes and 12-month guarantee as everywhere else.

After the work

Keep the joints in good shape with a few simple steps:

  • Make mastic part of routine maintenance checks
  • Avoid piecemeal callouts where you can
  • Make it easy for occupiers to report draughts
  • Check the asbestos register before any old mastic is disturbed

If a joint we sealed fails within 12 months, tell us and we will look at it. Beyond that, routine checks spot the next round of repairs.

Left open, joint edges in render, brick or frames can deteriorate. Once that happens, repairs come before resealing and the job grows.

Owners, agents and contractors

We work for building owners and managing agents on everything from one building to a spread of sites. Several sites can go on one quote, so there’s one set of paperwork to deal with.

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’ll confirm with the quote.
