For outside work, also let us know about exposed walls and any outbuildings involved.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.

About our external mastic in Hartfordbridge
External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant rarely last long. We strip the joint back and start again. We work on façade panels, render & cladding joints and joints between brick and frames, and common reasons people get in touch are leaking joints around cladding and façade panels and gaps where render, brick and frames meet.
External sealant needs dry, clean surfaces, so work around Hartfordbridge is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

Common questions in Hartfordbridge
Will you come out to Hartfordbridge?
Yes, Hartfordbridge is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near Winchfield station?
Yes. We work for landlords and letting agents as well as homeowners. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear price.
How long will you be here?
As a guide, most jobs take a few hours to a few days, depending on the length of joint and the access. Larger jobs naturally take longer, and we will say how long yours will take.
Can you do several jobs on one visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We’ll give you the cure time for the product we used.
Is it worth trying it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Can you seal joints between render and window frames?
Yes. Different materials move at different rates, so a flexible sealant is needed where they meet. We choose one that suits both surfaces.
Is there a guarantee?
Yes, for a year. If there’s a problem with our work in that time, tell us and we’ll put it right.
When something else is needed
A few problems are outside what sealant work can do:
- Walls that need new movement joints cut into them
- Render that’s blown, hollow or coming away
- Cracking across the wall rather than at a joint
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly.

How we quote for external mastic
Every job gets its own quote. These are the things that affect it:
- The number and length of the joints
- The type of sealant required
- Working hours on commercial sites
- The old material and how stubborn it is
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
What to tell us for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- The address or postcode of the job
- Any access issues, like height or stairs
- What’s wrong with the joints now
- The type of property

Hartfordbridge buildings and the weather
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For an older house near a landmark such as All Souls Church, older walls, gutters and the joints where extensions meet them need a flexible sealant. If you let a flat or house near Winchfield station, split movement joints are easy to miss on a rental until damp shows inside.
Hartfordbridge is about 3 miles south-west of Yateley, in Hampshire.

Near you in Hartfordbridge
Locally, jobs take us to homes and businesses close to The Cricketers pub. For rail, the closest station is Winchfield station, about 2.3 miles south of the centre.

Why deal with it now?
Sealing over the top of old mastic doesn’t hold for long. New sealant does not bond well to old, weathered sealant, so we always take the old sealant out. In a small place like Hartfordbridge, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

Aftercare tips
To keep the joints looking good and working properly:
- Keep soil, plants and ivy away from the joints
- Keep water from gutters off the wall
- Walk round the building once a year and look at the joints
- Make sure movement joints are not pointed over
Only paint over the joint if we have confirmed the sealant can take paint. Paint can crack on a flexible joint, and paint can crack as the joint moves.
Gaps, plants or missing sealant in a joint are worth getting looked at. Early work is quicker and leaves a better finish.
Do you need external mastic in Hartfordbridge?
Some movement joints have been pointed up with mortar, often by someone who didn’t know what it was for. The joint cannot move, so the wall cracks somewhere else instead.
Signs it’s time to call us include:
- Movement joints with cracked, split or missing sealant
- Rain getting behind render or cladding at a joint
- Failed sealant between panels on a façade
- Weeds or debris growing in open joints
If you look after a building such as Oakwood Infant School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
Before booking anyone
- What insurance they hold
- How the joint is cleaned and prepared
- Whether they seal over old material or remove it
- How much experience the applicator has

DIY sealant or a professional job?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
