Owners, agents and contractors
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, with each stage agreed with your site contact.
If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.
Mastic sealing in Rotherbridge
On a residential block, the work happens around people’s lives. Dates, areas and the order of work are agreed with you in advance so you can let residents know what is happening. Communal entrances and stairs stay usable while we work. The enquiries we see most involve failed external movement joints and draughts at frames across a block, across external wall and movement joints, shopfronts below residential blocks and communal kitchens and washrooms. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Rotherbridge, that means joint design, primers and backing rod as standard.
In and around smaller places like Rotherbridge, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Mastic around frames and on external joints wears out in time, whatever the building.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

Do you need mastic sealing in Rotherbridge?
Topping up old mastic is a common shortcut. New sealant won’t grip failed sealant, so these repairs rarely last.
What tends to prompt an enquiry:
- Failed external movement joints
- Draught complaints from residents or tenants
- The same joint failures repeated across a portfolio
- Leaks at window and door perimeters
For a school such as Petworth Cof E Primary School, perimeter mastic on windows and doors is a holiday job.
What your quote should include
- Their approach to joint depth and backing
- The named product and why it was chosen
- Whether primer will be used where the manufacturer specifies it
- Their pre-qualification and accreditations
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. Then we strip out anything that has failed, prepare every joint and seal it. Rural sites near Rotherbridge may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.
- We inspect the joints, building by building, and record what has failed and why.
- A fixed quote follows, split by block or building if that suits you.
- The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- We remove the old mastic completely and clean the joint faces back.
- 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.
Preparing the site
- Have the specification and drawings to hand
- Flag any permit to work we’ll need
- Point out parking and an unloading spot

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.

Questions we are asked in Rotherbridge
Will you take on a block within reach of Pulborough station?
Yes, and several blocks can go on one quote. We work to your notice and access arrangements.
Is Rotherbridge too small for you to travel to?
Not at all. Rotherbridge is within our area. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
Can people stay in the building while you reseal?
We plan around people living or working in the building. Dates and areas are agreed with you so residents or tenants can be told, and entrances stay in use.
Is asbestos a concern with old mastic?
In older buildings, old mastic can contain asbestos. We ask for the asbestos register or survey before work starts, and if it’s suspected, work stops until it’s tested.
Will you just go over the old sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
How long does a job like this take?
That varies with the scale of the job, but the work normally takes a few days for most blocks, with larger programmes scheduled building by building. For bigger or phased jobs, we will set out a timescale with the quote.
Doing it in-house
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
For owners and agents in Rotherbridge
Two care or nursing homes sit less than 2 miles from Rotherbridge. Frame mastic on care buildings is best renewed elevation by elevation, with the manager deciding timings. Rotherbridge sits in one of the drier corners of the country, the South East. Even so, frame mastic only goes on in dry, workable conditions, and the sunniest, most exposed sides of a building usually need attention first.
With historic buildings such as Petworth House (to the north-east of Rotherbridge) in the wider area, owners of older properties around Rotherbridge should expect mastic to need a product that suits old masonry. For owners of several units at places like Hampers Common Industrial Estate, 1.6 miles to the north-east of Rotherbridge, one programme can deal with frame and external mastic across the lot.

The countryside around Rotherbridge includes Bignor Hill and Graffham Common.
Why deal with it now?
A bead run over old mastic can look like a repair. It doesn’t bond and usually fails within a short time. Cutting out and resealing properly does it once. Around Rotherbridge, it’s better to renew all the failing joints at once, rather than one at a time. Send photos of each area and we will quote for the lot.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
