Lower Nazeing Window Mastic
Window and door frames in Lower Nazeing need attention? We cut out the old, prepare the joints and apply the right sealant.
- Hard, cracked sealant around windows
- Draughts coming in around windows and doors
- Mastic that is falling out in pieces
What we do, step by step
Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a morning for a couple of windows and a door. In a smaller place like Lower Nazeing, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Before we arrive
- Mention if the joints have been sealed before
- Mention any sign-in or site rules at work premises
- Plan for the work area to be out of bounds to pets and children

Advice
Window mastic in Lower Nazeing
The mastic around a window or door seals the gap between the frame and the wall. When it cracks, hardens or pulls away, draughts and rain get in. The old mastic is removed and the joint resealed with a flexible exterior sealant. If you have rushed sealant from a window installation and leaking joints at the ends of sills, we can put it right, whatever the surface.
Many houses in smaller places like Lower Nazeing have conservatories, garden rooms or patio doors. Their glazing joints and frame seals are as much a part of the job as the windows.

Window mastic in Lower Nazeing: local notes
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.
Managing a site like Nazeing Primary School? Then its window and door frames need their mastic kept sound, just like a home’s. In the older streets around St Giles, the joint between an old wall and a newer frame is usually the first place rain gets in.

Can I do it myself?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
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.
Common questions in Lower Nazeing
Is Lower Nazeing within the area you cover?
Yes, Lower Nazeing is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you cover Lower Nazeing for window mastic?

Can you reach windows above the ground floor?
Yes, where they can be reached safely. Let us know about access when you ask for a quote and we’ll plan for it.
Can resealing stop a draught around my window?
Yes, where the draught is at the frame edge. We find where the air is coming from before we reseal.
Do you have insurance?
Yes. We are fully insured for every job we do.
Will it make a mess?
Tidy work is part of the job. We protect what’s around the joints.
Is the new sealant paintable?
Silicone generally will not take paint. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
Can you match the sealant to my frames?
Yes. We can use white, brown, anthracite grey, black or clear.
Surface by surface
Window sills
Every drop off the glass ends up on the sill, so the sill ends and the joint under the frame are vital. Each is cleaned out and resealed.
Composite doors
An exposed front door gets wind-driven rain, and the top and bottom corners tend to fail first. We pay most attention there.

Do you need window mastic in Lower Nazeing?
Some failures date back to when the windows were fitted. Mastic laid onto dusty, damp or crumbling surfaces never bonded as it should, so it comes away long before its time.
The problems people normally mention when they call are:
- A bead that does not match the frame
- Cracked or shrunken mastic around the frame
- Gaps where the sill meets the wall
- Gaps left after new windows were fitted
Letting a property close to Broxbourne station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
What your quote should include
- Which sealant they’ll use, and why

Honest limits
It helps to know what we cannot do too:
- Faulty window hardware
- A door that needs adjusting, rehanging or new seals
- A frame that has rotted at the joint
