How the job changes by surface
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. That movement goes into the joint, so the sealant in it must stay soft and stretchy.
Concrete and blockwork
The face of concrete or block is often dusty, so cleaning and priming matter. A primer goes on where the product requires one before the bead.
External mastic for homes and businesses in Hambledon
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product. We work on copings & trims, façade panels and joints between brick and frames, and people most often call us about joints pointed up with cement by mistake and joints where the bead has come unstuck.
Outside joints can only be sealed when they’re dry, so work in Hambledon is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
Every job is covered by a one-year guarantee.

What affects the cost of external mastic
Jobs vary more than people expect. What affects the quote:
- The number and length of the joints
- The old material and how stubborn it is
- How many areas need sealing
- Whether the work is at height
Doing several joints on one visit usually makes better use of the time than several visits. We will give you a clear quote for the lot.
What we need to know
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- What’s wrong with the joints now
- If it’s domestic, commercial or a hotel
- How we’d reach the joints
- How many joints, rooms or windows are involved
We do not publish a price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, ring 0345 464 0079 or drop us an email.
Outside joints around Hambledon
Rainfall in the South East is lower than in much 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 Church of St Peter and St Paul, the joints between older walls, newer extensions and the roofline need a sealant that can move.
Hambledon is about 4 miles north-west of Horndean, in Hampshire. Anywhere in PO7, we can carry out external mastic at your property. Hambledon is one of 683 places in Hampshire where we work. For nearby work, see our Portsmouth page.
Every address in PO7 is within our area for external mastic, from the main roads to the quietest streets. That includes homes and businesses on High Street, West Street and The Maltings. Other places close to Hambledon include Anthill Common (1 mile south), Denmead (2 miles south-east), Anmore (3 miles south-east), Lovedean (3 miles south-east) and Wecock Farm (3 miles south-east).

Why it’s worth doing now in Hambledon
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That matters on brick, render and concrete, which can be weaker at the face. A stiffer product can damage the joint edge as it fails. Around Hambledon, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.
Why us?
- Fully insured
- 20+ years of sealant experience
- We agree the colour with you first
- White, clear, grey or another colour, product permitting
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
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 doesn’t work out, we can still put it right.
Common questions in Hambledon
Is there a guarantee on external mastic in Hambledon?
All our work, in Hambledon and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Is Hambledon within the area you cover?
Yes. Hambledon is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We’ll tell you what we are using and why.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Will you leave a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
I’m a tenant. Can you help?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.
Do you use backing rod?
That’s backing rod, a closed-cell foam. It keeps the sealant at the right depth and bonded to the sides only so it can flex with the joint.
What do you need from me for a quote?
Only a few details: the address or postcode, what’s wrong and any access issues. Then call 0345 464 0079 or send us an email.
Common problems we fix in Hambledon
Weeds, moss and debris in a joint are a sign the sealant has gone. Roots and dirt hold water against the wall.
Look out for these signs:
- Leaking joints around cladding and façade panels
- Gaps where render, brick and frames meet
- Water getting into walls through failed joints
- Joints with sealant missing in places
Schools such as Hambledon Primary School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.
Questions to ask before you book
- What preparation is included
- The length of the guarantee

How it works
You don’t need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the work takes anything from a few hours to several days, depending on the building for a typical job. Somewhere as small as Hambledon, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Getting ready for the visit
- Tell us about any previous sealing or DIY attempts
- Try not to wet indoor joints just before the visit
