Milford on Sea Window Mastic
Problem with your window and door frames in Milford on Sea? We cut out the old, prepare the joints and apply the right sealant.
- Rushed sealant from a window installation
- Draughty joints inside around the window
- White mastic on grey or black frames
Surface by surface
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We can talk through the options.
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A neat, narrow bead in a colour to match suits the frame.
About our window mastic in Milford on Sea
If you can feel air around a shut window, the gap is often at the frame. A new joint stops the air getting through. If the draught is through the window seals instead, we will tell you. If you’re dealing with damp patches on the reveal after heavy rain and cold air getting in at the frame edge, we can put it right, whatever the surface.
In a smaller place like Milford on Sea, some walls face open ground and catch the full force of the weather. The mastic around frames on those walls tends to age faster.
You are covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or email us.

Windows and doors in Milford on Sea
Milford on Sea is close to 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 the mastic around window and door frames, 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, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you let a flat or house near Lymington Town station, renewing tired window mastic between tenants heads off draught and damp complaints. If you look after a building such as Milford-on-Sea Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages. For an older house near a landmark such as Church of All Saints, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

How to look after the new joints
So the new joints stay in good condition:
- Keep drainage slots and sill grooves clear
- Walk round the house once a year and look at the joints
- Keep paint off silicone joints
- Avoid harsh chemicals near the mastic
Silicone can’t usually be painted, so mention any painting plans before work begins. There are paintable sealants for joints that need it.
A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and a cold room gets colder. A new joint closes it up.
Why deal with it now?
Not every sealant suits a window. Interior caulk and bathroom silicone aren’t made for exterior frame joints. An exterior, low-modulus sealant stays flexible in sun and frost. In a smaller place like Milford on Sea, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

Questions from Milford on Sea
Do you cover smaller places like Milford on Sea?
Yes. Milford on Sea 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.
Does the coastal weather in Milford on Sea affect outside sealant?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you do not need to watch us work.
Can new sealant go over the old?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
Can you do the inside joint as well?
Yes. Plenty of draughts come through the inside joint as well as the outside, so it can be worth sealing both.
How long does it take to reseal the windows on a house?
The work takes a few hours for a few frames, or a day or more for a whole house. Access and how stubborn the old mastic is affect the time most.
Can new window sealant be painted?
Not usually, if it’s silicone. Tell us your decorating plans and we’ll pick a sealant to suit.
What we do, step by step
Before we leave, we go over the finished joints with you. The work normally takes most of a day for a typical house, less for a few frames, depending on the size of the job. For a job in Milford on Sea, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Mention any parking rules near the property
- Mention any leaks or damp you’ve noticed
