Window & door mastic in Albury, Hertfordshire
Problem with your window and door frames in Albury? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- Draughty joints inside around the window
- Cracked sealant at the sill ends
- Water coming in at the bottom corners of a door
Window mastic in Albury
A window frame and the wall around it expand and shrink at different rates. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. So the sealant has to stretch and recover, which is why we use a low-modulus product. We work on composite doors, patio & French doors and aluminium frames, and people most often call us about draughty joints inside around the window and rain getting in at the frame or under the sill.
Mastic can only go onto a dry, clean joint, so window work in Albury is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
Whatever the size of the job, it’s backed by our one-year guarantee in Albury and across Hertfordshire.

When it is not the sealant
We will not take on work that won’t last, so here’s what sealant can’t put right:
- Worn gaskets, brush seals or a door that has dropped
- Misting between the panes of a double-glazed unit (that needs a new unit)
- A frame that has rotted at the joint
Not sure which it is? You can call 0345 464 0079 or send us an email and we’ll tell you honestly.

What happens on the day
You do not need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the job takes a morning for a couple of windows and a door in most cases. Somewhere like Albury needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away, along with any loose debris.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Mention any leaks or damp you’ve noticed
- Mention any parking rules near the property

What does window mastic cost?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.

Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.

Do I have to be there?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.

Window mastic in Albury: local notes
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. Historic houses like Much Hadham Palace (about 3.6 miles south) are a reminder that the area around Albury has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
For landlords with property near Bishops Stortford station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Managing a site like Albury Church of England Voluntary Aided Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.

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
Timber moves with moisture as well as heat, so a flexible sealant is essential. The paint or stain needs to be sound where the sealant meets it.
What affects the quote in Albury
You’ll get a clear quote before we start. It takes into account:
- The number of rooms or windows
- The old material and how stubborn it is
- Any mould that needs treating
- How easy the joints are to reach
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
What we need to know
When you call or email, it’s useful to know:
- How many joints, rooms or windows are involved
- Photos by email, if that is easy
- Any access issues, like height or stairs
- The problem you’ve noticed
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job.
DIY versus a professional finish
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
What we are called out for in Albury
On timber frames, paint and putty build up around the joint. Old mastic gets painted over and cracks under the paint, and timber moves with moisture as well as temperature.
Look out for these signs:
- Black, perished sealant on frames
- Draughts coming in around windows and doors
- Hard, cracked sealant around windows
- Damp patches on the reveal after heavy rain
For an older house near a landmark such as Church of St Mary, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Questions to ask before booking
- What the quote includes, VAT included or not
- Who turns up on the day
- Whether all the old sealant comes out first
- Which sealant they’ll use, and why
