What we do, step by step
There’s no need to move everything out, just the space around the work. We protect the rest, and the work takes most of a day for a typical house, less for a few frames in most cases. Outdoor work around Powfoot depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- We start by checking each window and door with you.
- We remove the old mastic and clean the frame and the wall.
- Deep gaps are filled with backing rod to set the depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- We clear up and check every joint is fully closed.
Before we arrive
- Mention if the joints have been sealed before
- On commercial sites, let us know about site rules
- Mention any leaks or damp you’ve noticed

About our window mastic in Powfoot
Behind a thin line of old mastic there’s sometimes a deep void. Filling it with sealant alone leaves a joint that can’t move properly, so we fit backing rod to set the right depth. The sealant then grips the two sides it should. We are often asked to deal with cracked sealant at the sill ends and gaps between the frame and the inside reveal, on window sills, uPVC windows and patio & French doors.
In and around a place like Powfoot, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain.
You’re covered for a year from the day we finish. If there’s a problem with it, please send an email to info@mrmastic.co.uk.

Why deal with it now?
The work is quick compared with the damage it prevents: the visit takes anything from an hour or two to a full day, depending on how many frames there are. Leave it until water is coming in and you may need plastering and decorating as well. Around Powfoot, water from a failed joint in an older stone home can soak into timber and plaster.
Doing several joints on one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

Different surfaces, different methods
Aluminium frames
Coated aluminium needs a compatible sealant and we avoid acetoxy silicones, which can react with some metals. We use a neutral-cure product.
Composite doors
Composite doors are normally hung in an uPVC-type frame, so its perimeter joint is sealed much like a window. We match the colour to the frame.
How we quote for window mastic
The price is agreed before any work begins. It takes into account:
- The old material and how stubborn it is
- The number and length of the joints
- Whether the work is at height
- Any working-time requirements on site
The cost reflects the work involved, not guesswork. That is why we ask a few questions first and send you a clear quote before we start.
Asking for a quote
Photos by email are helpful but not essential. Try to tell us:
- Any previous sealing or DIY work
- The rough size of the job
- Pictures of the joints, sent by email
- The address or postcode of the job
There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To get started, email us at info@mrmastic.co.uk.

DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
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.
Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Keep paint off silicone joints
- Look round the frames every year or so
- Wipe condensation off the frames
- Don’t use solvent cleaners on the joint
Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak, and if anything looks wrong, just drop us a line at info@mrmastic.co.uk.
On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so it pays to reseal before that happens.
FAQs for Powfoot
Can you help a landlord with a rental near Annan station?

Is window mastic in a coastal place like Powfoot any different?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Can you get sealant to suit coloured frames?
Yes, in most cases. Mention the frame colour when you ask for a quote and we’ll match it as closely as we can.
Will resealing my frames help with draughts?
Yes, where the draught is at the frame edge. We find where the air is coming from before we reseal.
Do I need to be at home?
That depends on where the joints are. Inside work needs someone to give us access.
Will you leave a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Where are you based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Do you work for hotels and businesses?
Yes. We can plan bigger jobs in stages.
Powfoot homes and the weather
Powfoot 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 the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.
For an older house near a landmark such as Cummertrees Parish Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Letting a property close to Annan station? Then renewing tired window mastic between tenants heads off draught and damp complaints.
