FAQs for Old Hawkinge
Will you come out to Old Hawkinge?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you help a landlord with a rental near Folkestone Central station?
Yes, we work for letting agents and landlords. Just ring 0345 464 0079 or email us and tell us about the property, and we will give you a clear quote.
Is there a guarantee?
Yes: twelve months. If there’s a problem with our work in that time, tell us and we’ll put it right.
Why is there a gap in my brick wall?
It’s a deliberate gap that lets the wall expand and contract without cracking. It should be filled with flexible sealant, never mortar.
Do you use backing rod?
Backing rod controls the sealant depth and keeps it off the back of the joint. That way it bonds to the two sides only and can stretch.
How long before the joint can be used?
Cure times vary by product and the temperature. Before we leave, we will tell you the cure time.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
What sealant do you use?
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.
How we handle external mastic in Old Hawkinge
A movement joint is a deliberate break that lets a wall expand and contract. Its sealant has to flex with the building, season after season, and when it fails, the wall takes the strain and water finds a way in. If you are dealing with rain getting behind render or cladding at a joint and movement joints with cracked, split or missing sealant, we can put it right.
Older homes in small places like Old Hawkinge may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points.
You are covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or drop us an email.

Honest limits
It helps to know what we cannot do too:
- Cracks in the bricks or render themselves, away from the joints
- Structural movement, which needs a surveyor or engineer
- Failed render or damaged cladding panels

Can I do it myself?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
When to call us in Old Hawkinge
Using the wrong sealant is another common reason. A high-modulus or general-purpose sealant can be too rigid for a busy joint, and it tears off the sides.
Signs it’s time to call us include:
- Joints pointed up with cement by mistake
- Weeds or debris growing in open joints
- Old sealant gone brittle and cracked
- Joints with sealant missing in places
Homes close to Church of St Michael include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.

What happens if it’s left?
Sealing over the top of old mastic does not hold for long. New sealant doesn’t bond well to old, weathered sealant, so the old joint is cut out fully first. Older cottages and farmhouses around Old Hawkinge can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

For landlords and businesses

Quotes for external mastic in Old Hawkinge
There’s no set price list, because no two jobs are the same. The quote depends on:
- Whether old sealant or filler has to be cut out
- Mould in or behind the old joints
- Working hours on commercial sites
- The product the joint needs
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, phone 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.
What we need to know
Before you ask for a quote, have a think about:
- What’s wrong with the joints now
- The rough size of the job
- The type of property
- Where the property is
We don’t publish a price list. Instead, your job gets its own clear quote. To get started, phone 0345 464 0079 or send us an email.
What external mastic looks like in Old Hawkinge
Old Hawkinge is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on movement joints and outside wall joints, especially on the side facing the sea. Historic houses like Acrise Place (about 2.7 miles north-west) are a reminder that the area around Old Hawkinge has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
Letting a property close to Folkestone Central station? Then outside joints that have cracked can let damp into a rental, so check them between lets. Schools such as Hawkinge Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

The process
On the day, we start by going over the job with you. Surfaces next to the work are protected before we start. Most jobs take a few hours to a few days, depending on the length of joint and the access. Somewhere as small as Old Hawkinge, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Plan for the work area to be out of bounds to pets and children
- Clear items away from the joints we’re working on
