Mastic sealing in Five Oaks
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Different surfaces, different methods
Communal areas
Joints at low level in communal areas take knocks from bins, bikes and buggies, so they often need renewing sooner.
Window and door perimeters on blocks
Window and door perimeters are where most mastic failure shows. Old perimeter mastic is removed, the joint prepared and new sealant tooled in.
Mastic sealing in Five Oaks, done properly
For over 20 years we have resealed joints for owners, agents and landlords. Every applicator holds a CSCS card, and the work is backed by public liability insurance. Resealed mastic joints in Five Oaks carry our 12-month guarantee. We work on external wall and movement joints, shopfronts below residential blocks and window and door perimeters on blocks, and the failures we are asked to look at most are complaints coming in block by block and draughts at frames across a block. A single leaking joint is often how a building in Five Oaks first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
In and around smaller places like Five Oaks, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Frame and wall-joint mastic on all of them ages and hardens.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Our process
Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. For work around Five Oaks, we aim to finish in one visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.
- First comes a look at the joints and, for older buildings, the asbestos records.
- A fixed quote covers the joints, products and order of work.
- Failed mastic is removed completely.
- The joints are prepared and resealed with the right product.
- We finish each building before moving to the next.
What we need from you
- Warn occupants and staff about the work
- Move anything stored against the joints
- Let us know about inductions and permits

Advice
Questions about Five Oaks
Will you take on work at estates like Billingshurst Trade Park, close to Five Oaks?
Yes. We cover Five Oaks and the area around it, including industrial estates, business parks and retail parks such as Billingshurst Trade Park. To start, just speak to us on 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.
Is Five Oaks too far out for you?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. 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?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.
Is asbestos a concern with old mastic?
Some mastics in pre-2000 buildings contain asbestos. We check the asbestos register or survey before disturbing it, and if it’s suspected, work stops until it’s tested.
How much does the work cost?
It depends on the job: quantities, access, the product and any phasing. Call for a quote.
Can people stay in the building while you reseal?
Occupiers stay in the building throughout. If any flats or units need access, we will tell you in advance so you can arrange it with occupiers.

What else we do in Five Oaks
Do you need mastic sealing in Five Oaks?
Occasionally the substrate fails, not the sealant, such as crumbling render, brick arrises or frame edges. If the edges are unsound, we say so before quoting the sealing.
Typical triggers for a call:
- Mastic failing across several blocks on an estate
- Brittle perimeter mastic across a building
- Damaged joints in communal entrances and corridors
- Open joints in brickwork or panels
Buildings close to stations like Billingshurst station, 2.2 miles south of Five Oaks, are often flats over shops, with frame mastic to keep sound.
What to look for in a quote

- Their pre-qualification and accreditations

- Whether old or failed sealant will be cut out, not overlaid
Why it’s worth doing now in Five Oaks
Draughts round window perimeters cost occupiers comfort, and they often blame the windows. In many cases, new perimeter sealant deals with it when the frames themselves are sound. Older rural buildings around Five Oaks move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we’ll explain how it’s made up.
