How the job changes by surface
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A tidy bead in anthracite grey, black or a matching colour suits the frame.
Timber windows & doors
Where timber has rotted at the joint, it needs repairing first. We will point out any rot we find, as a joiner will need to deal with it.
Window mastic for homes and businesses in Benderloch
Some gaps around frames are far deeper than they look. Filling it with sealant alone leaves a joint that can’t move properly, so deep gaps get backing rod first. The sealant then grips the two sides it should. We work on aluminium frames, uPVC windows and composite doors, and the jobs we see most are gaps left after new windows were fitted and gaps between the frame and the inside reveal.
In and around a place like Benderloch, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill.
Whatever the size of the job, you get the same 12-month guarantee.

Honest limits
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Condensation trapped between the panes
- Broken hinges, locks or handles
- A frame that has rotted at the joint

Window mastic in Benderloch: local notes
Benderloch 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. Benderloch is in the west of Scotland, which is wetter than the east, which means the mastic around window and door frames has to cope with a lot of rain.
For landlords with property near Connel Ferry station, renewing tired window mastic between tenants heads off draught and damp complaints. In and around Benderloch, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

The process
There’s no need to move everything out before we come, only the area right around the joints. Everything nearby is protected, and the work takes anything from an hour or two to a full day, depending on how many frames there are in most cases. Outside jobs in Benderloch 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.
- We check each frame and agree which ones need doing.
- Next the failed sealant is cut away and the joint cleaned.
- We fit backing rod in deep gaps so the sealant is the right depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Finally we tidy up and check each joint.

Your questions about window mastic in Benderloch
Is window mastic in a coastal place like Benderloch 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 help a landlord with a rental near Connel Ferry station?
Yes, landlords and agents are among the people we work for. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we will give you a clear price.
Can you do upstairs windows?
Yes, if safe access is possible. For high or awkward windows, we’ll tell you what access is needed.
Should I try DIY first?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
What sealant do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Is the work guaranteed?
Yes. All our work carries a 12-month guarantee, and we are ARBOMaster approved applicators.
Do the sealants smell?
There can be a smell while the sealant cures. Opening a window helps.
What should I tell you?
A short description and the location, with pictures by email if possible. We will ask anything else we need to know.

Landlord and commercial work in Benderloch
Letting agents and landlords in Benderloch can book us as well as homeowners. Sealant work between tenants keeps a property looking cared for.
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will quote.
Should I try it myself first?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
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.
Keeping the joints in good condition
After the cure time, these simple habits help:
- Avoid blasting the frames with a pressure washer
- Look round the frames every year or so
- Keep solvents and bleach off the sealant
- Wipe condensation off the frames
Clean the frames with mild soapy water, and keep solvents and harsh chemicals off the joint.
Signs to watch for: split or missing mastic, gaps, damp patches inside or black mould on the reveal. If you notice one, it’s time to get the joint looked at.
