Frames and glazing around Longniddry
Longniddry 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 the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Historic houses like Gosford House (about 1.8 miles north) are a reminder that the area around Longniddry has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you let a flat or house near Longniddry station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

How we handle window mastic in Longniddry
Homes in Longniddry have every kind of window: uPVC, aluminium, timber and composite, along with patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. Typical jobs include damp patches on the reveal after heavy rain and gaps between the frame and the inside reveal, on timber windows & doors, patio & French doors and window sills.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Wind-driven rain finds any gap around a frame or sill, so the mastic there works hard.
Every job is covered by our one-year guarantee, wherever you are in East Lothian.

Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Air rooms to keep condensation down around windows
- Keep paint off silicone joints
- Wash the frames with mild soapy water
- Keep timber frames painted
Clean the frames with mild soapy water, and keep solvents and harsh chemicals off the joint.
Wet, windy weather is when failed mastic shows itself, but sealant goes on best when frames and walls are dry. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
FAQs for Longniddry
Does the coastal weather in Longniddry affect outside sealant?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. Walls facing the sea are generally the first to need attention.
Is Longniddry within the area you cover?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
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 will match it as closely as we can.
When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint.
Do you work on first-floor windows?
Yes, as long as they can be reached safely. Let us know about access when you ask for a quote so we can plan the job.
What information do you need?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply drop us a line at info@mrmastic.co.uk.
Are you fully insured?
Yes. We are fully insured, with over 20 years’ experience in sealant work.
Does the work come with a guarantee?
Yes, with our 12-month guarantee. Keeping drainage clear and checking the joints yearly helps them last.
Common problems we fix in Longniddry
Mastic ages in the weather. UV light hardens the outside of the bead, and over the years it loses its give, cracks and comes away.
People generally contact us after spotting something like this:
- Untidy mastic left by window fitters
- Cracked or shrunken mastic around the frame
- Sealant in the wrong colour for the frame
- Gaps where the sill meets the wall
Historic houses such as Gosford House, about 1.8 miles north, show how far back building around Longniddry goes, and older homes nearby need a sealant that suits their walls.
Questions to ask before booking

What affects the quote in Longniddry
The quote reflects the job in front of us. We look at:
- Working hours on commercial sites
- Mould in or behind the old joints
- How much old sealant there is and how hard it is to remove
- How many areas need sealing
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before we start, so you know where you stand.
What we need to know
Photos help, but a description is a good start. Try to tell us:
- The type of property
- Any previous sealing or DIY work
- The address or postcode of the job
- Roughly how big the job is
For a quick quote, get us on the phone, or email us if that is easier. Tell us about the joints that need doing and we’ll explain what’s involved and give you a clear quote.
What we do, step by step
We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. Most jobs take a morning for a couple of windows and a door. In smaller Scottish places, parking is generally less of an issue than access and distance. Let us know how to find you and how to reach the joints.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely, along with any loose debris.
- The surfaces are cleaned and left dry.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
How to prepare
- Keep pets and children clear of the area while we work
- Let us know if you’ve seen damp or leaks
- Tell us about any previous sealing or DIY attempts

Landlord and commercial work in Longniddry
If you manage several properties in or around Longniddry, several properties can be quoted together. Send us the addresses and the work at each, and photos by email help.
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
The difference is mostly in the preparation and the 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.
Why deal with it now?
Redecorating is a good moment to renew the mastic. Fresh joints finish the job neatly, and it’s easier while the walls are being worked on anyway. In an older home around Longniddry, damp from a failed joint can get into timber and plaster.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
