Mastic sealing across Goodley Stock
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Mastic sealing in Goodley Stock, done properly
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 will 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 kitchens and washrooms, and the failures we are asked to look at most are the same joint failures repeated across a portfolio and old repairs sealed over failed mastic. A single leaking joint is often how a building in Goodley Stock first comes to us: we look at the rest while we’re there and tell you what we find.
For owners with a single building near Goodley Stock, we plan to finish in one visit where possible. Send photographs of the frames and joints and we will give a fixed quote.
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.

For managing agents and facilities managers
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.
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
How the quote is worked out
To price the job, we consider:
- Access and working height
- Location, for remote and island sites
- The total length or number of joints
- Removal of failed or old sealant
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.
Details that help us quote
A good diagnosis starts with the right details. Let us know:
- Specification clauses that apply
- Where the site is, with the postcode
- Approximate linear metres or a joint schedule
- What the building is and how it’s used
Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. The easiest way is to ring 01277 525 020 or send photos by email.
What happens if it’s left?
Resealing ahead of leaks keeps it to a maintenance task. After water has got in, there may be damp, damaged plaster or decoration to put right too, and the complaints come with it. Halls, stores and units around places like Goodley Stock may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
Why appoint us
- Public liability insurance in place
- Colours confirmed for the specified product
- CHAS accredited contractor
- Specification-led, product-correct work
Your questions answered
Is Goodley Stock too small for you to travel to?
No. Small places get the same service as large ones. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
Can you quote for a block close to Hurst Green station?
Yes, and several blocks can go on one quote. We work to your notice and access arrangements.
Will residents or tenants be disturbed?
We plan around people living or working in the building. We agree the programme so you can notify occupiers and communal access is kept open.
Do you seal on top of existing sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Is asbestos a concern with old mastic?
We don’t remove asbestos-containing materials. Anything suspect is tested before we carry on in line with the dutyholder’s asbestos management.
Does the weather affect the work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Who decides which product is used?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
After the work
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Share the asbestos register when you send details
- Make it easy for occupiers to report draughts
- Protect low-level joints in entrances
- Log resealing dates block by block
Include sealant in planned building inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away, and note the building and elevation.
Planned resealing is easier to budget than emergency repairs. We can quote buildings in priority order and work down the list.
What the job involves on each surface
Planned maintenance
Adding mastic to planned maintenance avoids reactive repairs and keeps budgets predictable.
Window and door perimeters on blocks
On most blocks, the frame-to-wall joint is where failure shows first. We remove the failed mastic, prepare the faces, add backing rod if the joint is deep and reseal.
From enquiry to sign-off
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work typically takes a day or two for a single block, longer for an estate programme, and our waste is bagged and taken away as we go. For work around Goodley Stock, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- We check the asbestos register for older buildings and look at the joints.
- A fixed quote covers the joints, products and order of work.
- We strip out the old sealant.
- Joint faces are cleaned, backed and resealed.
- Buildings are completed in turn.
Getting the site ready
- Move anything stored against the joints
- Agree which areas must stay open
- Explain the parking and delivery arrangements

Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.
