Landlord and commercial work in Lower Slackstead
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Window mastic in Lower Slackstead, done properly
There are two joints on most windows. Outside, the mastic keeps rain out; inside, the joint between frame and plaster stops draughts and tidies the reveal. We seal one or both, depending on what’s needed. Common call-outs are for rushed sealant from a window installation and hard, cracked sealant around windows, on uPVC windows, window sills and composite doors.
In a village or hamlet like Lower Slackstead, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
Whatever the size of the job, it’s backed by our one-year guarantee in Lower Slackstead and across Hampshire.

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Keep paint and stain on wooden frames in good order
- Keep solvents and bleach off the sealant
- Clean frames with a soft cloth and soapy water
- Look round the frames every year or so
Have a look at the joints once a year, ideally after winter. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just call 0345 464 0079 or drop us an email.
Water trapped behind a failed joint can start rot in timber frames and sills. Once wood has rotted, it needs repair before it can be sealed, so it pays to reseal before that happens.
Windows and doors in Lower Slackstead
With historic houses such as Mottisfont Abbey (about 4.3 miles west) nearby, there’s older building stock in the area around Lower Slackstead as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you live in an older home near Church of All Saints, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Rented homes near Romsey station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints.

I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
Can you work on commercial sites?
Yes. We can plan bigger jobs in stages.

What affects the quote in Lower Slackstead

- Working hours on commercial sites
- The product the joint needs
- How much old sealant there is and how hard it is to remove

What happens if it’s left?
A cracked joint around a frame lets rain into 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 Lower Slackstead can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost depends on the size of the job, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts.
What you get with us
- Over 20 years’ experience
- White, clear, grey or coloured to suit, where the product allows
- A sealant colour to suit the surroundings
- Old sealant always removed completely
What we cannot put right
New sealant cannot fix everything, and we’ll tell you before work begins. It won’t solve:
- Damp problems in the wall away from the window
- A door that needs adjusting, rehanging or new seals
- Rotten timber, which needs a joiner first
If you’re not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer before booking.
Joints and surfaces we work on
- Patio & French doors
- Composite doors
- Window sills
- Timber windows & doors
- uPVC windows
- Aluminium frames
Different surfaces, different methods
Patio & French doors
Not every patio door leak is a mastic problem: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We look for the cause first.
Composite doors
An exposed front door gets wind-driven rain, and the top and bottom corners tend to fail first. Those corners get the most care.
