Window Mastic in Whitecairns
Our applicators work in Whitecairns on mastic around window and door frames, sills and patio doors. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Water coming in at the bottom corners of a door
- Cold air getting in at the frame edge
- Gaps where the sill meets the wall
Window mastic for homes and businesses in Whitecairns
Every window and door frame has a gap around it, and mastic is what closes it. Once that seal fails, wind and rain find the gap. The old mastic is removed and the joint resealed with a flexible exterior sealant. If you have black, perished sealant on frames and cold air getting in at the frame edge, we can put it right.
Mastic can only go onto a dry joint, so outside work in Whitecairns depends on the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
There’s a 12-month guarantee on every job.

Leave it or put it right?
Resealing frames is a short job: the visit takes a morning for a couple of windows and a door. Wait for damp to appear and there may be plaster and decorating to sort out too. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
The cost depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts.

How we quote for window mastic
Jobs vary more than people expect. The main factors:
- The old material and how stubborn it is
- When we can work, for business premises
- The size of the job
- The product the joint needs
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.
What we need to know
What to tell us when you ask for a quote:
- The problem you’ve noticed
- How we’d reach the joints
- How many joints, rooms or windows are involved
- Whether it has been sealed before
For a quick quote, get us on the phone, or email us if that is easier. Describe what needs sealing and we will talk you through the work before giving you a price.
When to call us in Whitecairns
Joint shape matters as much as the product. A thin smear across a wide gap has nothing to it, and a gap filled solid can’t flex. Backing rod sets the right depth.
People usually contact us after spotting something like this:
- Cold air getting in at the frame edge
- Rushed sealant from a window installation
- Mastic that is falling out in pieces
- A bead that does not match the frame
Around Whitecairns, as everywhere, window mastic is only as good as the preparation behind it.
What to look for in a quote
- How much experience the applicator has
- How long to leave it before use
- Whether VAT is included
- Which sealant they’ll use, and why
What window mastic looks like in Whitecairns
Aberdeen is known as the Granite City, and granite is hard and dense, so any sealant against it needs clean, sound edges to grip. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
For landlords with property near Dyce station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Aftercare tips
So the new joints stay in good condition:
- Air rooms to keep condensation down around windows
- Keep drainage slots and sill grooves clear
- Don’t paint over the silicone
- Keep paint and stain on wooden frames in good order
Check the drainage slots in the frames are not blocked, so water can run away instead of sitting against the joint.
Signs to watch for: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. If you notice one, it’s time to get the joint looked at.
Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

How many windows can you do in a day?
Allow a morning for a couple of windows and a door. Access and the amount of old mastic make the biggest difference.
Should I try DIY first?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
How the visit works
When we arrive, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before any work begins. The work normally takes a morning for a couple of windows and a door. Outside jobs in Whitecairns need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- 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.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- Clear the area around the work
- Try not to wet indoor joints just before the visit

Advice

Different surfaces, different methods
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. The threshold and the bottom corners take the most water, so we pay close attention there.
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the threshold joint takes a lot of water. Each is cleaned, backed where deep and resealed.
