What window mastic looks like in Navestock Side
With historic houses such as Hill Hall (about 4.8 miles west) nearby, there’s older building stock in the area around Navestock Side as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

How the job changes by surface
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. The threshold and the bottom corners take the most water, so they get particular care.
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. We cut it out, back any deep gaps and reseal properly.

What else we do in Navestock Side
How it works
You do not need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the job takes most of a day for a typical house, less for a few frames in most cases. Somewhere like Navestock Side needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely, along with any loose debris.
- The surfaces are cleaned and left dry.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Preparing for the visit
- Clear the area around the work
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any leaks or damp you’ve noticed

What affects the cost of window mastic
For a quick quote, just ask. The main things that affect it are:
- Any working-time requirements on site
- The size of the job
- Which sealant suits the joint
- How many rooms, windows or areas are involved
Doing several joints on one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.

When to call us in Navestock Side
Joint shape matters as much as the product. A skim of sealant over a wide gap soon tears, while a joint packed solid can’t stretch. Backing rod sets the right depth.
If you can see any of these, it’s time to have the joints looked at:
- Rain getting in at the frame or under the sill
- Whistling draughts around closed windows
- Cracked or shrunken mastic around the frame
- Sealant in the wrong colour for the frame
If you live in an older home near Church of St Paul, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Landlords, agents and businesses in Navestock Side

We also work for property managers and facilities teams. We can quote a run of properties together, and we’re fully insured.
DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Do the sealants smell?

Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint.

The work takes anything from an hour or two to a full day, depending on how many frames there are. Access and the amount of old mastic make the biggest difference.

Generally, yes. Mention the frame colour when you ask for a quote and we will use the nearest match.
