Blocks and managed buildings in Mackerel's Common
Mackerel's Common is in the South East, one of the UK’s drier regions. External mastic still waits for dry faces and the right temperature, while the elevations that take the most sun tend to show hardened mastic first. Central London is about 37 miles from Mackerel's Common. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres; their frame mastic often ages block-wide.
Historic properties like Petworth House (4.6 miles south-west of Mackerel's Common) show the age of some local stock, where frame mastic must suit soft brick or stone. If you’re responsible for a building such as The Parish Church of St John the Baptist, frame and door mastic needs the same attention as any other property.

Questions we are asked in Mackerel's Common
Can one quote cover a number of our buildings near Mackerel's Common?
Yes. Planned programmes across a building, block or estate are a core part of this service. Send the addresses and photographs and we’ll give a fixed quote.
Is Mackerel's Common too far out for you?
No. Places such as Mackerel's Common are covered as much as the big towns. London and every South East county are within our area. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
Does weather matter for sealant work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
Will residents or tenants be disturbed?
Occupiers stay in the building throughout. If any flats or units need access, we’ll tell you in advance so it can be arranged.
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 are CHAS accredited and a Constructionline member.
Will you just go over the old sealant?
No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
What the job involves on each surface
External movement joints
Brickwork, blockwork and panel joints let a building move. Failed sealant in a movement joint lets water in.
Planned maintenance
We can work into your cyclical maintenance plan, building by building.
Keeping the joints sound
Regular inspection catches problems early. In particular:
- Share the asbestos register when you send details
- Log resealing dates block by block
- Group repairs into a planned programme
- Keep bins and bikes away from communal door frames
Keep bins, bikes and deliveries away from low-level joints where you can. Damage at low level is the most common reason communal joints fail early.
The longer failed joints are left, the more likely the substrate edges break up. Then the edges may need repairing first and the job grows.
Why deal with it now?
Draughts round window perimeters cost occupiers comfort, and they often blame the windows. Resealing the perimeters is often the simpler fix where the frames themselves are sound. One visit to deal with every failing joint makes more sense than several trips to a place like Mackerel's Common, rather than one at a time. Photos of every joint help us quote for the whole job.
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 sealant work can’t fix
Sealant solves a lot, but not everything, and we’re upfront when that’s the case. These need a different solution:
- Misted or failed double-glazed units
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Leaks through the frame itself rather than the perimeter
If in doubt, call 01277 525 020 or use the quote form and we’ll say what we think.
Joints and surfaces we work on
- External wall and movement joints
- Communal kitchens and washrooms
- Shopfronts below residential blocks
- Window and door perimeters on blocks
- Communal entrances and stairwells
- Balcony and threshold joints
When to call us in Mackerel's Common
We often find joints filled solid with no backing rod so the mastic is bonded on three sides. It can’t stretch properly and splits as the building moves.
Typical triggers for a call:
- Water getting in round frames after rain
- Complaints coming in block by block
- Movement joints with sealant missing
- Old repairs sealed over failed mastic
Blocks of flats and mixed-use buildings often cluster around stations such as Billingshurst station (to the south-east of Mackerel's Common) and their window and balcony mastic tends to age at the same rate across a building.
Questions to ask before you book
- What the guarantee covers, and for how long
- How joint depth will be controlled
- Are they CHAS accredited or on Constructionline?
- Whether old or failed sealant will be cut out, not overlaid
Our process
We begin with a short walk round with whoever looks after the building, 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. For a building around Mackerel's Common, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.
- Each block or building is walked and the failed joints recorded with the likely cause.
- 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.
- 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.

- Confirm the product named in the specification
