Construction mastic in Roundbush, done properly
The specification and the programme set the job rather than whatever product is to hand. Where the specification names a product, we use it. Joint widths, backing, primers and tooling follow the manufacturer’s guidance. If you have window and door perimeters that won’t pass inspection and sealant knocked or painted over by other trades, we can put it right, on floor and skirting junctions, internal decorators’ caulk and sanitary and kitchen joints alike. Most enquiries from Roundbush start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
In the countryside around places like Roundbush, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Do you need construction mastic in Roundbush?
A new building moves while it dries and settles. Plaster, screeds, timber and blockwork all shrink as they lose moisture, which opens up internal joints, particularly where caulk has been used in a joint that moves. Choosing the right product for each joint reduces that.
Look out for the following:
- Mastic snags holding up handover
- Old sealant on a refurbishment that needs stripping before new work
- Different trades sealing to different standards
- Cracks opening in caulked internal joints
For contractors at a school such as Cold Norton Primary School, sealing has to be finished before term starts.

Why deal with it now?
When a package runs over budget, downgrading the product is a common first thought. A failed joint in the defects period costs far more than the product difference and external joints are where it shows first. We price the specified product and will tell you plainly where an alternative would or wouldn’t work. Converted and older buildings near places like Roundbush tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

Site staff or a sealant specialist?
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
When it isn’t the sealant
We check first that sealant really is the fix. It isn’t the answer for:
- Frame gaps too wide for sealant, which the installer needs to correct
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
- Glazing units that are cracked or misted
If in doubt, ring 01277 525 020 or email a schedule or drawings and we’ll say what we think before you book.

Different surfaces, different methods
Bathrooms, en suites and washrooms
Across a block of flats or a hotel, sanitary sealing is repeated in every room. A single team keeps the standard consistent following the programme.
Snagging before handover
Snags usually come from damage by following trades, missed joints or poor earlier work. Snagging can be included or priced separately, depending on what suits the programme.
From enquiry to sign-off
On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself normally taking a few days on a modest refurbishment and longer on multi-plot or multi-storey schemes. Jobs in and around smaller places like Roundbush are usually planned as a single visit, so photos and measurements up front really help. Then the right materials arrive with us.
- First we look at the scope on site or from drawings.
- A fixed quote sets out scope, products and phasing.
- Paperwork is agreed and applicators are inducted on site.
- We seal plot by plot or floor by floor in line with the programme.
- Problems we find, such as oversized gaps, are raised right away.
- The package is closed out, snags cleared and backed by our 12-month guarantee.
What we need from you
- Tell us your opening times and when work is allowed
- Send any specification or drawings in advance
- Share the asbestos register for older buildings

Your questions answered
Does the sea air around Roundbush change the choice of sealant?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We check the specified product suits the exposure and pay close attention to preparation.
Will you take on work at estates like Mapledean Industrial Estate, close to Roundbush?
Yes, sites like Mapledean Industrial Estate are within our area, along with the rest of Roundbush. A few photos and the unit address let us price the work.
Do you work in Roundbush?
Yes. Roundbush falls within our area, and you can give us a call on 01277 525 020 or email the details over to get started.
What site paperwork can you supply?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
What accreditations do you hold?
Our applicators hold CSCS cards, and we’re CHAS accredited and a Constructionline member. We are also fully insured, with five million pounds of public liability cover.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
How do you work with the site programme?
The programme sets the job. Share the release dates and we’ll match our work to them.
Sites and facades in and around Roundbush
With the shore within about 3 miles, Roundbush counts as a coastal location. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, and the sealant, primer and backing need choosing with that in mind. Central London is about 36 miles from Roundbush. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, so mastic packages have to keep pace with busy programmes.
Recladding or extending a unit at a site like Mapledean Industrial Estate (1.1 miles south-east of Roundbush) brings panel joints and frame perimeters into the programme.
