Northbridge Street Window Mastic
Problem with your window and door frames in Northbridge Street? We cut out the old, prepare the joints and apply the right sealant, with a 12-month guarantee.
- Gaps between the frame and the inside reveal
- Hard, cracked sealant around windows
- Rushed sealant from a window installation
How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Do not aim a pressure washer at the joints
- Use gentle cleaners on frames and sealant
- Don’t paint over the silicone
- Check the mastic once a year
Keep the new mastic undisturbed while it cures, following the cure time we give you. Keep jet washers away from the frames.
Water trapped behind a failed joint can start rot in timber frames and sills. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.
Window mastic in Northbridge Street
Over two decades of sealing frames has taught us which products suit which walls. We’re ARBOMaster approved and fully insured, and we give a one-year guarantee on the work. If you’re dealing with hard, cracked sealant around windows and rushed sealant from a window installation, we can put it right, on composite doors, window sills and patio & French doors alike.
Somewhere as small as Northbridge Street, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
Whatever the size of the job, it’s backed by our 12-month guarantee.

Surface by surface
Composite doors
Composite doors are normally hung in an uPVC-type frame, and the joint around it is sealed like a window. The bead is colour-matched to the frame.
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. We cut it out, back any deep gaps and reseal properly.
What affects the cost of window mastic
The quote reflects the job in front of us. We look at:
- When we can work, for business premises
- Which sealant suits the joint
- The old material and how stubborn it is
- The number and length of the joints
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or drop us an email.
What to tell us for a quote
When you call or email, these details help:
- Any previous sealing or DIY work
- Roughly how big the job is
- Any access issues, like height or stairs
- What the problem is, such as mould, gaps, leaks or cracking
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is. Whenever you are ready, call 0345 464 0079 or email us.
What happens on the day
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a few frames, or a day or more for a whole house. For a village or hamlet like Northbridge Street, the journey is planned in advance: let us know about lanes, gates and parking. 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.
- 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.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Try not to wet indoor joints just before the visit
- Mention any tricky access

Advice
What happens if it’s left?
Choosing the product is half the job. Decorators’ caulk and bathroom silicone are not designed for outside joints that move. A low-modulus exterior sealant keeps its stretch through hot and cold weather. Older cottages and farmhouses around Northbridge Street can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Combining jobs into one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will give you a clear quote for the lot.

Honest limits
Some problems need a builder, plumber or other trade rather than us:
- A sash or casement that will not close properly
- Penetrating damp from a failed cavity tray or render
- Misting between the panes of a double-glazed unit (that needs a new unit)
Not sure which it is? You can call 0345 464 0079 or send us an email and we’ll tell you honestly before you book.

Northbridge Street homes and the weather
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Durhamford Manor (about 3.9 miles south-east) are a reminder that the area around Northbridge Street has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Schools such as Salehurst Church of England Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. For an older house near a landmark such as The Parish Church of St Mary, the joint between an old wall and a newer frame is usually the first place rain gets in. If you let a flat or house near Robertsbridge station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
