External mastic for homes and businesses in Beaulieu
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. We pick a colour that sits well with the wall so the line blends in. We work on brickwork movement joints, render & cladding joints and copings & trims, and people most often call us about moss and dirt in joints with no sealant left and joints pointed up with cement by mistake.
In a village or hamlet like Beaulieu, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
Big or small, you get the same 12-month guarantee in Beaulieu and across Hampshire.

How it works
On the day, we look over the joints with you first, so you know exactly what we are doing. Surfaces next to the work are protected before work begins. Most jobs take a few hours to a few days, depending on the length of joint and the access. Somewhere as small as Beaulieu, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, the joints are inspected and the access agreed.
- 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.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
How to prepare
- Try not to wet indoor joints just before the visit
- Plan for the work area to be out of bounds to pets and children
- Let us know about parking restrictions

Related advice
What we’re called out for in Beaulieu
If plants are growing out of a joint, the sealant has generally failed or was never there. Roots and dirt hold water against the wall.
Keep an eye out for any of the following:
- Weathered mastic that no longer stretches
- Movement joints filled with mortar instead of sealant
- Rain getting behind render or cladding at a joint
- Leaking joints around cladding and façade panels
In the older streets around Church of the Blessed Virgin and Child, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
What your quote should include
- What insurance they hold
- How hidden problems are handled
- How the surfaces are prepared before sealing

Beaulieu questions
Does living near the coast affect external mastic in Beaulieu?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Will you come out to Beaulieu?
Yes. Beaulieu is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
What is a movement joint?
Brickwork, render and cladding all move a little, so long walls have planned gaps to take that movement. The gap is sealed with a flexible sealant over backing rod.
How do I get a quote for external mastic in Beaulieu?
Every job is different, so each one gets its own quote. For a quick quote, ring 0345 464 0079 or send us an email with a short description of the job.
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.
Can tenants book the work?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.
Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all.
Landlord and commercial work in Beaulieu
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
What happens if it’s left?
Running new sealant over the old bead rarely lasts. The new layer can’t bond properly to old, weathered material, so we always take the old sealant out. In a small place like Beaulieu, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

What external mastic looks like in Beaulieu
Beaulieu is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Managing a site like Beaulieu Village Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. For landlords with property near Beaulieu Road station, split movement joints are easy to miss on a rental until damp shows inside.

Around Beaulieu

Nearby you’ll also find Lymington New Forest Hospital (5.4 miles south-west) and Beaulieu Abbey And Display Of Monastic Life (within half a mile north-west).
Should I try it myself first?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

- Any mould that needs treating
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.
