About our glazing silicone in Anna Valley
Glass replacement is not something we do and a misted double-glazed unit needs a glazier. What we do is the silicone around the glass and that is often where the water gets in. We work on glass-to-frame joints, shower screens and conservatory frames, and the jobs we see most are water running down inside the glass and black or yellowed silicone on glass joints.
Outdoor sealant needs dry, clean surfaces, so work on frames around Anna Valley is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
Whatever the size of the job, it’s backed by our 12-month guarantee.

Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
When to call us in Anna Valley
Some conservatory leaks are not sealant at all: broken panels, roof problems and blocked gutters can all let water in. We find the cause before we seal anything.
People normally contact us after spotting something like this:
- Drips on the inside of a conservatory window
- Leaks from the base of a shower screen
- Leaks where conservatory glass meets the frame
- Glass-to-glass joints that have split
Rented homes near Andover station change hands often, and leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.

Leave it or put it right?
Resealing cannot fix a failed unit or a cracked panel. We say so plainly, so you can call the right trade. In a small place like Anna Valley, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we’ll go through it with you.
What you get with us
- Sanitary silicone with an anti-fungal additive in wet areas
- Homes, businesses and hotels
- Approved under the ARBOMaster scheme
- Any old sealant cut out fully, not covered over

What sealant work can’t fix
Sealant is not the answer to every problem, and we’d rather say so up front. It will not solve:
- Cracked or broken glass
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
- A sagging or failing conservatory roof
If you’re not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer before booking.
Joints and surfaces we work on

How the visit works
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours, depending on how many joints need doing, and the area is left clean. In a small place like Anna Valley, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we agree the joints to be done.
- Old sealant is removed from the glass and frame.
- We clean and prepare the joint.
- We apply and tool the new silicone.
- We inspect the work and test it where we can.
Before we arrive
- Tell us if parking is tricky
- Keep children and pets away from the work area
- Tell us about any water getting in

Surface by surface
Rooflights
Rooflights get the full force of the weather. The sealant around the glass and frame wears faster than most.
Glass balustrade bases
We reseal the joint where the glass meets the base channel. We do not install or replace glass.
Windows and doors in Anna Valley
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For an older house near a landmark such as Church of All Saints, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Managing a site like Balksbury Junior School? Then the mastic around its windows and doors needs looking after like any other building’s.
