About our window mastic in Smannell
Over two decades of sealing frames has taught us which products suit which walls. We are ARBOMaster approved and fully insured, and every job is covered by a 12-month guarantee. If you have mastic that’s falling out in pieces and hard, cracked sealant around windows, we can put it right.
In a village or hamlet like Smannell, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
There’s a 12-month guarantee on every job.

DIY sealant or a professional job?
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.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Smannell questions
Will you come out to Smannell?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you cover Smannell for window mastic?
Yes, Smannell is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or drop us an email and let us know what needs doing.
Do you do commercial work?
Yes. We’ve worked for hotels, offices and other businesses.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
I rent my home. Can I book you?
We’re happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.
Can you seal over the old sealant?
No, it will not last. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.
How many windows can you do in a day?
The work takes a few hours for a handful of frames, longer for a whole house. Access and how stubborn the old mastic is affect the time most.
Is it messy?
We keep the work tidy. Nearby surfaces are protected, and the area is left clean when we finish.
Leave it or put it right?
Once mastic fails, rain can get between the frame and the wall. Over time that can mean damp patches, damaged plaster and rotting timber. Resealing now is a small job by comparison. Older cottages and farmhouses around Smannell can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
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, and we’ll explain the quote if you ask.

When to call us in Smannell
Older frames were often sealed with products that set hard. Once it’s rigid, every bit of frame movement pulls at it, and a gap opens along one edge.
Keep an eye out for any of the following:
- Cold air getting in at the frame edge
- Hard, cracked sealant around windows
- Untidy mastic left by window fitters
- Old mastic that has gone black or come away
If you let a flat or house near Andover station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

How the job changes by surface
Patio & French doors
Patio and French doors have the longest joints on most houses. The threshold and the bottom corners take the most water, so they get particular care.
Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We can talk through the options.

Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Use gentle cleaners on frames and sealant
- Repaint timber before it’s bare
- Don’t use solvent cleaners on the joint
- Ventilate rooms so frames don’t stay wet inside
Wipe the frames with soapy water when you clean the windows, and keep solvents and harsh chemicals off the joint.
Wet, windy weather is when failed mastic shows itself, but resealing works best in dry conditions. Sorting cracked mastic early means the joint is sound before the bad weather.
Frames and glazing around Smannell
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Schools such as Smannell and Enham Church of England (Aided) Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. For an older house near a landmark such as Christ Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

When it is not the sealant
New sealant can’t fix everything, and we’d rather say so up front. Sealant won’t put right:
- Rotten timber, which needs a joiner first
- A failed sealed unit that has misted up
- A sash or casement that won’t close properly

How it works
You don’t need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the work takes a few hours for a few frames, or a day or more for a whole house in most cases. Somewhere like Smannell needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
How to prepare
- Move anything stored near the joints
- Tell us about any previous sealing or DIY attempts
- Keep pets and children clear of the area while we work
