Let us know how to find you and how to reach the joints.
- We start by checking each surround and agreeing the joints to renew.
- Old, loose mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- We dress the surface so it sits neatly against the masonry.
Before we arrive
- Keep pets and children clear of the area while we work
- Let us know about stairs, lifts or work at height
- For indoor joints, keep the area dry beforehand if you can

Sand mastic in Port Henry, done properly
Our applicators renew the sand mastic around sash and case windows and doors in stone and brick. Out comes the old, loose mastic, and new mastic is applied and shaped by hand. Common call-outs are for old cement repairs round a window that have failed and a silicone bead on a sash window that spoils the look, across period & listed homes, timber door frames and stone surrounds.
Outdoor sealant needs a dry surface, so window work around Port Henry is planned around the weather. Tell us about access to all the windows and doors, upstairs included.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Port Henry: your questions answered
Is sand mastic in a coastal place like Port Henry any different?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. Walls facing the sea are usually the first to need attention.
Is Port Henry within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Do you work for landlords and businesses?
Yes. We work for homeowners, landlords, letting agents, businesses and hotels in Port Henry.
Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.
When will the new mastic be hard?
It skins over fairly quickly but takes longer to harden fully. We’ll tell you what to expect for your job.
Can you quote for more than one area?
Yes, we can. More than one area can go on one quote.
Are you ARBOMaster approved?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Leave it or put it right?
Before painting the windows, it pays to renew the mastic. Paint over cracked mastic will not stop the gaps and traditional guidance is to leave the new mastic unpainted. In an older home around Port Henry, damp from a failed joint can get into timber and plaster.
The cost depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.
Why us?
- Neat joints and a tidy finish
- Quality sealants from Arbo and Everbuild
- 20+ years of sealant experience
- Anti-fungal silicone where joints get wet

How we quote for sand mastic

Helping us quote
Before you ask for a quote, have a think about:
- Any access issues, like height or stairs
- Roughly how big the job is
- If someone has resealed it before
- Pictures of the joints, sent by email
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Do not run silicone over sand mastic
- Check the mastic when you check the paintwork
- Keep sills and gutters clear so water drains away
- Get any rot dealt with first
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens.
DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
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.
Port Henry homes and the weather
Port Henry is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around older windows and doors, especially on the side facing the sea. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
In and around Port Henry, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.
