Mastic sealing across Steyning
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
General trades versus a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
How we handle mastic sealing in Steyning
Managing agents and housing associations usually need paperwork before anyone starts. 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, with public liability insurance. We work on external wall and movement joints, shopfronts below residential blocks and communal entrances and stairwells, and what we’re called in for most is communal area joints that look neglected and no planned programme for sealant. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Steyning is the same: the right product in a properly prepared joint.
For landlords and associations with stock in and around Steyning, grouping buildings into one visit saves travel. One quote can cover a whole list of addresses.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

On site: what to expect
The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. If neighbouring businesses or buildings around Steyning need work too, visits can be combined. Mention the building’s opening times and we will work within them.
- We check the asbestos register for older buildings and look at the joints.
- A fixed quote covers the joints, products and order of work.
- Failed mastic is removed completely.
- Joint faces are cleaned, backed and resealed.
- We finish each building before moving to the next.
Getting the site ready
- Point out parking and an unloading spot
- Tell us your opening times and when work is allowed
- Point out any areas we must not close

Advice
FAQs: Steyning
Will you take on a block within reach of Lancing station?
Yes, and several blocks can go on one quote. Photos of each elevation help us quote accurately.
Is Steyning off your patch?
Not at all. Steyning is within our area. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
Do you guarantee the mastic work?
A 12-month guarantee covers our work. It applies to our workmanship rather than damage or problems with the frames.
How long before the joints can be used?
We will confirm how long the chosen product needs to cure.
Can you plan resealing across several buildings?
Yes. Each building is inspected, quoted and scheduled in turn starting wherever is most urgent.
Do you check for asbestos in old sealant?
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.
Do you supply RAMS and insurance details?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We hold CHAS accreditation and Constructionline membership.
For owners and agents in Steyning
Steyning is about 44 miles from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres; their frame mastic often ages block-wide. Steyning sits in one of the drier corners of the country, the South East. Outside work still depends on dry joints, and south- and west-facing elevations, which take the most sun and rain, often age first.
For owners of several units at places like Mackley Industrial Estate, which lies east of Steyning, one programme can deal with frame and external mastic across the lot. Schools and community buildings such as Steyning CofE Primary School need frame and external mastic kept sound like any building.
Steyning is about 4 miles north-west of Shoreham-by-Sea, in West Sussex. Any commercial site in Steyning is covered, for single jobs and planned programmes alike. Steyning is one of 373 places in West Sussex on our list. Our Brighton page has more on work in that area (9 miles or so).

Owners, agents and contractors
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.
Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.
Why it’s worth doing now in Steyning
Draughts round window perimeters cost occupiers comfort and the windows usually get the blame. Resealing the perimeters is often the simpler fix where the frames themselves are sound. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.
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.

Cost factors for mastic joints
Your fixed quote is built from the real scope. It takes account of:
- Joint width, depth and condition
- Site requirements such as inductions and permits
- The total length or number of joints
- How much existing material needs removing
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.
What we need to price the job
A good diagnosis starts with the right details. Tell us:
- Photos of the joints, close up and from further back
- What the building is and how it’s used
- Rough lengths or quantities, or drawings if you have them
- The postcode of the building
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.
