Surface by surface
Concrete and blockwork
Concrete faces can be dusty and porous, so cleaning and priming matter. We prime where the sealant needs it before sealing.
Copings and trims
Coping and trim joints face rain and sun head on. Each is resealed with a weatherproof, flexible sealant.
How we handle external mastic in Holborough
We’re ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Some surfaces need a primer before sealing. If you are dealing with brick movement joints where the sealant has split and weathered mastic that no longer stretches, we can help, whatever the surface.
Houses in smaller places like Holborough can stand more in the open than those in a built-up town, so exposed walls and rooflines take more wind-driven rain. Joints on those sides are generally the first to go.
A one-year guarantee comes as standard, so you’re not left on your own once the job is done.

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
External mastic in Holborough: local notes
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Starkey Castle (about 1.9 miles north) nearby, there’s older building stock in the area around Holborough as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
For an older house near a landmark such as Church of the New Jerusalem, older walls, gutters and the joints where extensions meet them need a flexible sealant. For landlords with property near Snodland station, outside joints that have cracked can let damp into a rental, so check them between lets.

Quotes for external mastic in Holborough
Every job gets its own quote. This is what makes a difference:
- Which sealant suits the joint
- Any mould that needs treating
- How many areas need sealing
- Access and height
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
Helping us quote
There’s no need for technical detail. Just tell us:
- How we’d reach the joints
- The type of property
- Whether it has been sealed before
- Where the property is
We quote each job on its own. Just phone 0345 464 0079 or send us an email with the details and send photos if you have them.
What we’re called out for in Holborough
Buildings move more than people expect. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. The sealant in the movement joints takes that strain.
Keep an eye out for any of the following:
- Hard, crazed mastic that has stopped moving
- Plants rooting in failed movement joints
- Panel joints letting water in
- Movement joints with cracked, split or missing sealant
For site and facilities teams at buildings such as Valley Invicta Primary School at Holborough Lakes, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

How the visit works
Before we leave, we go over the finished joints with you. The visit itself generally takes anything from a few hours to several days, depending on the building, depending on the size of the job. A visit to Holborough is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- Old sealant and any debris are cut and raked out.
- Both sides are cleaned back to sound material and primed if needed.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Before we arrive
- Mention any tricky access
- Plan for the work area to be out of bounds to pets and children
- Move anything stored near the joints

FAQs for Holborough
I let a flat near Snodland station. Can you help?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear quote.
Do you cover smaller places like Holborough?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
How long does external mastic take?
That depends on how much there is to do, but most jobs take a few hours for a handful of joints, longer for a whole elevation. We will tell you when we quote.
Do you use backing rod?
Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. That way it bonds to the two sides only and can stretch.
Does someone need to be in?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Will you leave a mess?
We keep the work tidy. We protect what’s around the joints, and we clear up when we are done.
What do you put in the joint?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Do you take out the old sealant first?
Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.
Keeping the joints in good condition
Looking after new joints is easy:
- Keep water from gutters off the wall
- Never let anyone fill a movement joint with mortar
- Show decorators and builders where the movement joints are
- Keep high-pressure jets off the joints
Don’t paint over the new sealant unless we’ve said the product is paintable. Many exterior sealants are not designed to be painted.
Act while the splits are small. Then it’s a straightforward cut-out and reseal before water has had years to get in.
