Landlord and commercial work in South Harewood
In hotels, rooms out of use cost money, so we plan the work room by room. We have worked in hotels as well as homes and businesses.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
About our glazing silicone in South Harewood
Sealant on glazing does not last for ever. Sun, rain and movement wear it down and cracked joints let water in. Renewing it keeps glazing joints doing their job. If you have conservatory leaks at frame and glazing joints and a quick top-up bead that didn’t last, we can put it right, on glass-to-glass joints, glass-to-frame joints and glass balustrade bases alike.
Homes in small places like South Harewood often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
Every job is covered by our 12-month guarantee.

What affects the cost of glazing silicone
Your quote is based on your job. We take into account:
- How many rooms, windows or areas are involved
- The number and length of the joints
- Which sealant suits the joint
- How easy the joints are to reach
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before we start.
What we need to know
Before you ask for a quote, have a think about:
- Any previous sealing or DIY work
- Where the property is
- A few pictures by email, if you can
- The type of property
We quote each job on its own, so the first step is telling us about yours. Simply call 0345 464 0079 or drop us an email and describe the job.
What happens on the day
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 we start. Most jobs take a few hours, depending on how many joints need doing. For a village or hamlet like South Harewood, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We trace the leak and confirm it’s a sealant joint.
- We remove the old sealant carefully.
- We clean the glass and frame so the new silicone bonds.
- We lay the new bead and tool it smooth.
- Each joint is checked and, where possible, water-tested.
Getting ready for the visit

Surface by surface
Glass balustrade bases
The base of a glass balustrade is generally sealed. Failed sealant there lets water collect.
Conservatory frames
The joints where the conservatory meets the house take a lot of movement. They’re resealed with a suitable sealant.
Honest limits
In fairness, there are a few things sealant will not fix:
- Cracked or broken glass
- A frame that needs repairing or replacing
- Failed flashing around a conservatory
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think.
Surfaces we seal
- Glass balustrade bases
- Rooflights
- Conservatory frames
- Glass-to-glass joints
- Shower screens
- Glass-to-frame joints
Why act early in South Harewood
Dealing with a leaking shower screen early protects the floor and ceiling. Water from a failed joint can soak into the floor before you notice. Where a wall is exposed, as many are in small places like South Harewood, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

South Harewood homes and the weather
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.
For site and facilities teams at buildings such as Wherwell Primary School, larger buildings have plenty of frames, and the mastic around each one ages. For landlords with property near Andover station, glazing joints are worth checking at the end of a tenancy, before a small leak grows.

Can I do it myself?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
