Frames and glazing around Howes
Howes is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around window and door frames, especially on the side facing the sea. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
Schools such as Annan Academy are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. For landlords with property near Annan station, renewing tired window mastic between tenants heads off draught and damp complaints.

Why it’s worth doing now in Howes
A quick bead over the top of old mastic looks like an easy fix, but new sealant can’t bond to old, crumbling mastic. It soon lifts and the leak carries on behind it. Proper resealing starts with removing the old joint. In an older home around Howes, damp from a failed joint can get into timber and plaster.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

How the job changes by surface
Composite doors
Composite doors are normally hung in an uPVC-type frame, and the joint around it is sealed like a window. The bead is colour-matched to the frame.
Timber windows & doors
Where timber has rotted at the joint, it needs repairing first. If we find rot, we’ll tell you before going ahead, as that is a job for a joiner.

What affects the quote in Howes
Jobs vary more than people expect. The main factors:
- The size of the job
- The product the joint needs
- How easy the joints are to reach
- The old material and how stubborn it is
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.
What to tell us for a quote
Photos by email are helpful but not essential. Try to tell us:
- If it’s domestic, commercial or a hotel
- A few pictures by email, if you can
- The address or postcode of the job
- Any previous sealing or DIY work
For a quick quote, get us on the phone, or send an email if you’d rather. Describe what needs sealing and we will talk you through the work and give you a clear quote.
When to call us in Howes
Mastic ages in the weather. Sunlight dries the surface out, and over the years it loses its give, cracks and comes away.
These are the problems we’re asked about most:
- Draughty joints inside around the window
- Black, perished sealant on frames
- Gaps where the sill meets the wall
- Sealant in the wrong colour for the frame
Homes close to Old Parish Church include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Before you book anyone
- Is VAT in the price?
- Which colour the sealant will be
- Is the old sealant removed completely?
- Who turns up on the day
Howes questions
Is Howes within the area you cover?
Yes, Howes is covered. We work across all of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Does the coastal weather in Howes affect outside sealant?
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.
Is it OK to seal over old sealant?
No, it will not last. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. We can talk about working times when we quote.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Do you have sealant for grey or black windows?
Yes, in most cases. Mention the frame colour when you ask for a quote and we’ll use the nearest match.
Can you do the inside joint as well?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We do one or both.
Do you work for landlords and businesses?
Yes. We work for homeowners, landlords, letting agents, businesses and hotels.
How the visit works
We bring everything the job needs with us, so you don’t need to buy or prepare anything. Once we have agreed what’s being done, we protect the area and start. It normally takes a morning for a couple of windows and a door. Around Howes, distance and access matter more than parking. Tell us how to find the property and how to reach the work.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
Preparing for the visit
- Tell us if parking is tricky
- Mention any sign-in or site rules at work premises
- Try not to wet indoor joints just before the visit
