Mastic sealing for commercial buildings in Ashurst
Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. Many prefer a planned programme to one-off visits, with each block quoted and scheduled in turn. If you’re dealing with open joints in brickwork or panels and window mastic that has split and shrunk, we can help, on communal kitchens and washrooms, window and door perimeters on blocks and communal entrances and stairwells alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Ashurst, that means joint design, primers and backing rod as standard.
For buildings around smaller places like Ashurst, we group work so one trip covers it. Photos of each elevation help us quote accurately.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

Different surfaces, different methods
External movement joints
External movement joints take up expansion and contraction. Once that sealant goes, rain can reach the wall.
Tenement and older buildings
Some old mastics in pre-2000 buildings contain asbestos and the register is checked before anything is disturbed. If it’s suspected, work stops until it’s tested.
Looking after buildings in and around Ashurst
At about 40 miles from central London, Ashurst is within reach of the capital. 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. Rainfall across the South East, Ashurst included, is lower than in many parts of the UK. Outside mastic still needs a dry joint and the right temperature, and elevations facing the sun and the prevailing weather are usually where frame mastic ages first.
Schools and community buildings such as Ashurst CofE Primary School need frame and external mastic kept sound like any building. For owners of several units at places like Hollands Lane Industrial Estate, 1.8 miles east of Ashurst, one programme can deal with frame and external mastic across the lot. Churches, halls and community buildings such as The Parish Church of St James are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.
Ashurst is about 7 miles north of Shoreham-by-Sea, in West Sussex. Commercial clients in Ashurst use us for work on mastic joints, as part of our coverage of West Sussex.

Questions about Ashurst
Is Ashurst too far out for you?
No. Places such as Ashurst are covered as much as the big 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 one quote cover a number of our buildings near Ashurst?
Yes. Portfolio-wide programmes are a regular request. Residents are given notice through you, and the work moves building by building.
How long does a job like this take?
We plan the time on site around your programme and access. You’ll have an expected duration with the quote.
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.
How do you choose the sealant?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Do you work for managing agents and housing associations?
Yes, block and estate work is a core part of what we do. We work through buildings in a planned order so you can plan around it.
Can you send RAMS and CSCS details before starting?
Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are CHAS accredited and a Constructionline member.
From enquiry to sign-off
We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. If others near Ashurst need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- We inspect the joints, building by building, and record what has failed and why.
- A fixed quote follows, split by block or building if that suits you.
- 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 as the joint requires, then the new bead is placed and tooled.
- Each building is checked on completion and the work carries our 12-month guarantee.
What we need from you
- Warn occupants and staff about the work
- Clear stock, furniture or equipment away from the joints
- Arrange parking or a loading space

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. For smaller jobs, photographs and a description will do.

Work for main contractors and building owners
FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.
What sealant work can’t fix
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Masonry that has broken away beside the joint
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
Not sure which it is? You can call the office on 01277 525 020 or email drawings and photos and we’ll tell you honestly.
Joints and surfaces we work on
- Communal kitchens and washrooms
- Shopfronts below residential blocks
- Communal entrances and stairwells
- External wall and movement joints
- Window and door perimeters on blocks
- Balcony and threshold joints
Should maintenance staff do it?
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
What affects the price in Ashurst
Each job is priced on its own details. The things that drive the figure:
- Location, for remote and island sites
- Which sealant the job calls for
- Backing rod, priming and other preparation
- Quantities, in metres or numbers
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
Before you send an enquiry
Whether it’s one area or a whole building, the same details help:
- Access details, including height
- Where the site is, with the postcode
- Rough lengths or quantities, or drawings if you have them
- The asbestos register, for older buildings
