External mastic for homes and businesses in Milford on Sea
Short cuts in external joints show up within a season or two. Overfilled joints, missing backing rod and sealant laid over old sealant all tend to fail early. We take the old material out and do it properly. If you have rain getting behind render or cladding at a joint and brick movement joints where the sealant has split, we can help, whatever the surface.
Around Milford on Sea, garages, outbuildings and extensions all add to the joints on the outside of a home. Gutter ends, garage door frames and the joints where an extension meets the house are typical spots for leaks.
Big or small, it’s backed by our 12-month guarantee.

What external mastic looks like in Milford on Sea
Milford on Sea is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you look after a building such as Milford-on-Sea Church of England Primary School, larger buildings have long runs of movement joint that eventually need resealing. If you live in an older home near Church of All Saints, an extension built onto an older house moves differently, and the joint between them takes the strain.
Milford on Sea is about 3 miles south-west of Lymington, in Hampshire. Homes, rented property, offices and hotels in Milford on Sea is covered for external mastic, old or new, large or small.

DIY versus a professional finish
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 fails, we can still redo it.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
What happens on the day
There is not much for you to do on the day. Show us the job and we will take it from there. The job generally takes a few hours to a few days, depending on the length of joint and the access. A visit to Milford on Sea is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- 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.
- We apply the sealant, tool it and check the whole run.
Before we arrive
- Tell us about any water getting in
- For indoor joints, keep the area dry beforehand if you can
- Mention any parking rules near the property
Ask for a quote
Getting a quote is simple: let us know the job and the location, and roughly how big it is. A few photos by email make the job easier to understand.
Advice
What sealant work cannot fix
In fairness, some problems need a different trade:
- Rising or penetrating damp from elsewhere in the wall
- Cracks in the bricks or render themselves, away from the joints
- Walls that need new movement joints cut into them

Landlord and commercial work in Milford on Sea
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Letting agents often deal with us directly. Tell us the address, the job and how access works and we’ll quote.
What the job involves on each surface
Copings and trims
Coping and trim joints face rain and sun head on. Each is resealed with a weatherproof, flexible sealant.
Cladding and façade panels
If the façade has a specified sealant, that’s what we use. Tell us what the building has when you get in touch.
Why deal with it now?
The longer a joint stays open, the more water the wall takes in. In cold weather, frost can damage wet brick and render, so the damage spreads beyond the joint. Homes in smaller places like Milford on Sea can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Call for a quick quote and we will explain what it covers.
What you get with us
- Over 20 years’ experience

Questions from Milford on Sea
Is external mastic in a coastal place like Milford on Sea any different?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Can you help a landlord with a rental near Lymington Town station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear quote.
Why do you put foam in the joint first?
Backing rod controls the sealant depth and keeps it off the back of the joint. Then the sealant bonds to two faces and can move.
Do you have insurance?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Is the work guaranteed?
Yes. All our work carries our one-year guarantee.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Are you ARBOMaster approved?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
How do you reach high-level joints?
It depends on the building. We work on joints that can be reached safely. Give us some details and we’ll confirm the access.
When to call us in Milford on Sea
Poor preparation causes many early failures: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The new sealant then lets go long before it should.
Keep an eye out for these signs:
- Rigid filler in a joint that should flex
- Damp patches traced to an open external joint
- Joints where the bead has come unstuck
- Cracked joints where brick meets render or frames
Letting a property close to Lymington Town station? Then outside joints that have cracked can let damp into a rental, so check them between lets.
