Common questions from Kent Street clients
Is Kent 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.
Is Oakendene Industrial Estate, near Kent Street, within your area?
Yes. We cover Kent Street and the area around it, including industrial estates, business parks and retail parks such as Oakendene Industrial Estate. To start, just call the office on 01277 525 020 or email the details over with the unit, the joints involved and your access times.
Can weather delay the job?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
Which sealant will you use?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.
Can you seal joints high up on a block?
Every block is different. We agree access with you at quote stage so there are no surprises.
Can you quote from photographs?
That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs normally get a visit.
Mastic sealing in Kent Street
Blocks are lived in, so access and disruption have to be thought through. The sequence, the areas and the dates are settled with you, giving you what you need to notify residents. Entrances and stairwells are kept in use while we work. The enquiries we see most involve occupiers reporting cold air round windows and brittle perimeter mastic across a building, across balcony and threshold joints, external wall and movement joints and shopfronts below residential blocks. Looking for mastic applicators who cover Kent Street? We have been sealing commercial buildings since 2005.
Around smaller places like Kent Street, older walls fitted with newer windows are a familiar sight. The mastic needs to suit an irregular masonry face and the look of the building.
The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Block-wide mastic in Kent Street
Kent Street is about 37 miles from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres, and window and balcony mastic on them tends to age at the same rate. The South East is one of the drier parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and south- and west-facing elevations, which take the most sun and rain, often age first.
For owners of several units at places like Oakendene Industrial Estate, 0.8 miles to the north of Kent Street, one programme can deal with frame and external mastic across the lot.
Kent Street is about 5 miles west of Burgess Hill, in West Sussex. Anywhere in RH13, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. 373 places across West Sussex fall within our area, including Kent Street.

What the job involves on each surface
Commercial and mixed-use buildings
Tenants in commercial buildings need to keep trading so the work is phased.
Communal areas
Low-level communal joints get damaged more than most and tend to fail first.
What affects the price in Kent Street
There’s no standard rate for sealant work, since sites vary so much. What we take into account:
- Distance, for remote addresses
- Phasing around occupants
- How much existing material needs removing
- Access and working height
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.
Before you send an enquiry
A few photographs plus some basic facts will normally do. It helps to include:
- Drawings or a marked-up plan, if available
- Asbestos survey details if the building is older
- Any specification or named product
- The postcode of the building
Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. To get it moving, speak to us on 01277 525 020 or send photos by email.

Diagnose, treat, sign off
When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, and the work normally takes a few days for most blocks, with larger programmes scheduled building by building. Jobs in and around smaller places like Kent Street are usually planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.
- First we look at the mastic on each building and note what needs replacing.
- We send a fixed quote that sets out the joints, the products and the programme.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- Old sealant is stripped and each face prepared back to firm material.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
What we need from you
- Make sure the joints can be reached
- Arrange parking or a loading space
- Let building users know which areas are affected
Request a quote
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, call the office on 01277 525 020 or email drawings and photos.

Building owners, agents and FMs in Kent Street
Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
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, which keeps the paperwork simple.
After the work
A few simple habits keep the new joints working:
- Start inspections with the most exposed faces
- Share your contractor requirements early
- Have the asbestos survey to hand for older buildings
- Encourage occupiers to report problems at frames
If a joint we sealed fails within 12 months, tell us and we’ll look at it. After that, regular inspection keeps the programme on track.
One failed perimeter usually means others on the same building are close so a single failure is a sign to check the rest. A planned reseal saves repeated visits.
Do you need mastic sealing in Kent Street?
Many failed joints were sealed without backing rod, so the mastic is glued to the joint bottom too. It can’t stretch properly and splits as the building moves.
What tends to prompt an enquiry:
- Patchy repairs in mismatched sealant
- Damaged joints in communal entrances and corridors
- Draught complaints from residents or tenants
- Water getting in round frames after rain
For owners and agents with buildings in or around Kent Street, block-wide mastic programmes deal with frames and external joints of the same age together.
What your quote should include
- Is the sealant right for the movement and the substrate?
- Whether primer will be used where the manufacturer specifies it
- Whether old or failed sealant will be cut out, not overlaid
- Their pre-qualification and accreditations
