Mastic sealing in Lower Hartlip
On a residential block, the work happens around people’s lives. The sequence, the areas and the dates are settled with you so you can let residents know what is happening. Communal entrances and stairs stay usable throughout. Site teams most often ask us about brittle perimeter mastic across a building and worn sealant at communal door frames, on balcony and threshold joints, shopfronts below residential blocks and communal kitchens and washrooms. Whoever orders the work in Lower Hartlip, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.
In and around smaller places like Lower Hartlip, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Frame and wall-joint mastic on all of them ages and hardens.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

From enquiry to sign-off
Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. For work around Lower Hartlip, we aim to finish in one visit, so we ask for photos 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.
- The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- We remove the old mastic completely and clean the joint faces back.
- 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.
Before we start on site
- Share your working hours and any access restrictions
- Explain the parking and delivery arrangements
- Clear stock, furniture or equipment away from the joints

Advice
After the work
After handover, these steps help:
- Make it easy for occupiers to report draughts
- Protect low-level joints in entrances
- Plan resealing building by building rather than complaint by complaint
- Have the asbestos survey to hand for older buildings
Log the date and extent of the resealing for each block. That makes future programmes easier to plan and gives you a history.
Budgets are easier to plan when sealant is part of planned maintenance. We can quote buildings in priority order and work down the list.
Site staff or a sealant specialist?
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
For owners and agents in Lower Hartlip
The sea is no more than about 3 miles from Lower Hartlip. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints; plan inspections around that. Lower Hartlip lies roughly 34 miles out from central London. Within reach of London, blocks run by agents and associations are common around stations, and window and balcony mastic on them tends to age at the same rate.
For owners of several units at places like Newington Industrial Estate, 0.6 miles to the north-east of Lower Hartlip, one programme can deal with frame and external mastic across the lot. For a school such as Hartlip Endowed Church of England Primary School, perimeter mastic on windows and doors is a holiday job.

Your questions answered
Will you take on a block within reach of Newington station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. We work to your notice and access arrangements.
Is Lower Hartlip too small for you to travel to?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
How long does a job like this take?
It depends on the scope, but the work typically takes one or more days per building, depending on the joint lengths and the access. For bigger or phased jobs, we will set out a timescale with the quote.
Can people stay in the building while you reseal?
Residents and tenants carry on as normal. We flag any areas that need internal access well before the dates so you can arrange it with occupiers.
Does weather matter for sealant work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
Is asbestos a concern with old mastic?
In older buildings, old mastic can contain asbestos. We check the asbestos register or survey before disturbing it, and if it’s suspected, work stops until it’s tested.
How long will the new sealant 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.
Cost factors for mastic joints
Quotes vary with the job. It mainly depends on:
- The site’s rules and procedures
- Specialist products, such as fire-rated or hygienic sealants
- How much existing material needs removing
- Travel to remote or island sites
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
Before you send an enquiry
We can often quote from photographs and a few details. It helps to include:
- Asbestos survey details if the building is older
- Any dates the work must fit around
- Clear photographs of the problem areas
- What the building is and how it’s used
Let us know the site, the scope and your timescale, and we will put a fixed quote together. To get it moving, call the office on 01277 525 020 or email a schedule or drawings.
Leave it or put it right?
Failed perimeter mastic lets cold air in around frames and the windows typically get the blame. Resealing the perimeters is often the simpler fix where the frames themselves are sound. Converted and older buildings near places like Lower Hartlip tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
A quote for mastic joints depends on how many there are, their condition and the access, plus any specification you’re working to. Ask us for a fixed quote.

What else we do in Lower Hartlip
Common problems we fix in Lower Hartlip
Frames, panels and masonry expand and contract through the year, and the sealant takes up that movement. A joint that was too narrow, too thin or the wrong product can’t cope long before it should.
Site and facilities staff are often the first to spot these:
- A mix of products and colours from past repairs
- Water getting in round frames after rain
- Occupiers reporting cold air round windows
- Estate-wide sealant that is simply worn out
Trustees of buildings like Church of St Michael can bring frame and external mastic into a planned maintenance list.
