Mastic sealing across Storrington
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
How we handle mastic sealing in Storrington
Before work starts, most agents and landlords want the documents in order. For documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are a Constructionline member and CHAS accredited, and we carry public liability insurance. We work on external wall and movement joints, window and door perimeters on blocks and communal entrances and stairwells, and the usual reasons a site gets in touch are failed external movement joints and mastic failing across several blocks on an estate. A single leaking joint is often how a building in Storrington first comes to us: we look at the rest while we’re there and tell you what we find.
For landlords and associations with stock in and around Storrington, grouping buildings into one visit saves travel. Send the addresses and photos and we will quote for all of them together.
Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Planned mastic for Storrington portfolios
Storrington sits in one of the drier corners of the country, the South East. 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. Storrington lies roughly 43 miles out from central London. Managed blocks of flats are a big part of commuter-belt property.
If you look after a block within reach of Pulborough station, 3.9 miles north-west of Storrington, frame and balcony mastic can be renewed on one programme. Churches, halls and community buildings such as The Parish Church of St Mary the Virgin are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.
Storrington is about 7 miles north of Worthing, in West Sussex. Across the RH20 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. 373 places across West Sussex fall within our area, including Storrington. For work in that direction, see our Brighton page (15 miles or so).
We cover the RH20 postcode districts. For a building on Windmill Copse, Wantley Lane and Field End or nearby, we can quote for mastic joints.

After the work
Cleaning and maintenance staff play a part too. Share these points with them:
- Mention RAMS, insurance or CSCS requirements up front
- Keep bins and bikes away from communal door frames
- Keep a record of when each building was resealed
- Make it easy for occupiers to report draughts
Log the date and extent of the resealing for each block. It helps plan the next round and shows what was done.
Mastic fails gradually, then all at once in a wet spell. Acting at the first signs keeps it a straightforward reseal and saves internal repairs.

Do you do block-wide mastic programmes?

Can you seal joints high up on a block?
We talk through access for each building when we quote. Tell us the number of storeys and whether scaffold or other access is planned and we will confirm the approach in the quote.
How the job changes by surface
Window and door perimeters on blocks
Window and door perimeters are where most mastic failure shows. We remove the failed mastic, prepare the faces, add backing rod if the joint is deep and reseal.
Planned maintenance
Mastic wears out like any building component; how fast comes down to movement, weather, UV and the product. Regular inspection is the best way to plan resealing.
Our process
We schedule the visit to fit the site hours and access windows you give us. While we’re working, the area stays contained and tidy, and your contact hears from us before we move to the next area. If neighbouring businesses or buildings around Storrington need work too, visits can be combined. Tell us your site hours and we will plan around them.
- 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 programme is fixed with you, including dates you can pass on to residents or tenants.
- Failed mastic is removed and the faces taken back to sound, dry material.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
Preparing the site
- Send your site hours and access windows
- Point out any areas we must not close
- Tell us what induction or permit system the site runs
Ask for a quote
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, give us a call on 01277 525 020 or email a schedule or drawings.

What else we do in Storrington
When something else is needed

- Misted or failed double-glazed units
If in doubt, phone 01277 525 020 or email the details over and we will say what we think.
Where we work in Storrington
- Window and door perimeters on blocks
- Communal entrances and stairwells
- Communal kitchens and washrooms
- Balcony and threshold joints
- External wall and movement joints
- Shopfronts below residential blocks
What we are called out for in Storrington
Buildings move with temperature and moisture, and every joint has to stretch and squeeze with them. If the joint or the product wasn’t suited to the movement, it splits long before it should.
Clients usually get in touch after noticing one or more of the following:
- Estate-wide sealant that is simply worn out
- Window mastic that has split and shrunk
- Damp patches beside frames
- Failed external movement joints
If you own or manage units on a site such as Wiston Business Park, which lies east of Storrington, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.
Before you book anyone
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Whether their applicators hold CSCS cards
- How the existing material will be dealt with
- Is the sealant right for the movement and the substrate?
What happens if it’s left?
A bead run over old mastic can look like a repair. It doesn’t bond and typically fails within a short time. Cutting out and resealing properly does it once. Over time, UV, weather and movement wear any sealant out. Renewing it in good time keeps the building weathertight.
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.
