About our mastic sealing in West Marden
Owners and agents usually inherit a building’s mastic rather than choose it and it slowly wears out: it sits round windows and doors, along external joints and through communal areas. When it hardens, splits or pulls away, water and draughts follow, and occupiers start reporting it. If you’re dealing with brittle perimeter mastic across a building and draught complaints from residents or tenants, we can put it right, on shopfronts below residential blocks, external wall and movement joints 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 West Marden, that means joint design, primers and backing rod as standard.
For buildings around smaller places like West Marden, we group work so one trip covers it. Photos of each elevation help us quote accurately.
Work we carry out comes with a 12-month guarantee. Should something we installed fail, call the office on 01277 525 020 or send details through our quote form and we’ll come back to it.

When to bring in a specialist
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Leave it or put it right?
Leaving failed external joints lets water reach the structure behind. That can lead to damp, staining and damage to finishes, which is harder to deal with than resealing. For buildings around smaller places like West Marden, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

When something else is needed
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Water coming in from the roof or rainwater goods
- Leaks through the frame itself rather than the perimeter
Not sure which it is? You can phone 01277 525 020 or email the details over and we will tell you honestly before you book.

What else we do in West Marden
After the work
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:
- Avoid piecemeal callouts where you can
- Mention RAMS, insurance or CSCS requirements up front
- Have the asbestos survey to hand for older buildings
- Keep a record of when each building was resealed
Log the date and extent of the resealing for each block. That makes future programmes easier to plan and shows what was done.
Joints on a building age together so a single failure is a sign to check the rest. A planned reseal saves repeated visits.
Blocks and managed buildings in West Marden
West Marden is about 53 miles from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres. The South East is one of the drier parts of the UK. Outside work still depends on dry joints, and elevations facing the sun and the prevailing weather are typically where frame mastic ages first.
With historic buildings such as Uppark, 2.6 miles north of West Marden, in the wider area, owners of older properties around West Marden should expect mastic to need a product that suits old masonry. Schools and community buildings such as Compton and Up Marden CofE Primary School need frame and external mastic kept sound like any building. Blocks of flats and mixed-use buildings often cluster around stations such as Rowlands Castle station (2.8 miles south-west of West Marden) and their window and balcony mastic tends to age at the same rate across a building.

Our process
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. Rural sites near West Marden may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.
- Each block or building is walked and the failed joints recorded with the likely cause.
- You get a fixed quote, priced per building where that helps your budgeting.
- The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- Old sealant is stripped and each face prepared back to firm material.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
What we need from you
- Move anything stored against the joints
- Flag any permit to work we will need
- Send asbestos survey details if the building is pre-2000
