Can I do it myself?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Window mastic for homes and businesses in Lullingstone
Most frames have an outside joint and an inside one. The external joint is the weather seal; inside, the joint between frame and plaster stops draughts and tidies the reveal. Either or both can be done. If you have white mastic on grey or black frames and whistling draughts around closed windows, we can put it right, on uPVC windows, aluminium frames and composite doors alike.
Outdoor sealant needs dry, clean surfaces, so work on frames around Lullingstone is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

Window mastic in Lullingstone: local notes
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Lullingstone Castle (about 0.1 miles east) nearby, there’s older building stock in the area around Lullingstone 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.
Rented homes near Eynsford station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

The process
Good joint work is mostly preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it normally takes a few hours for a few frames, or a day or more for a whole house. Somewhere like Lullingstone needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First we look at every frame and agree the list.
- The old mastic is cut out and the surfaces cleaned back.
- Deep gaps are filled with backing rod to set the depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Finally we tidy up and check each joint.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- For business premises, tell us about site rules or sign-in
- Mention any parking rules near the property

Do you need window mastic in Lullingstone?
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.
People generally contact us after spotting one of these:
- Rushed sealant from a window installation
- Cracked internal joints between frame and plaster
- Gaps where the sill meets the wall
- Old mastic that has gone black or come away
In the older streets around Church of Saint Botolph, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Is Lullingstone within the area you cover?

What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We will tell you what we’re using and why.
How much does window mastic cost in Lullingstone?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we will talk you through it.
How many windows can you do in a day?
It depends on access, the old mastic and the size of the frames. You’ll know the timing when we quote.
Can you do several jobs on one visit?
Of course. Doing several areas at once is generally more efficient.
Can new window sealant be painted?
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.
Will you leave a mess?
Tidy work is part of the job. We protect what’s around the joints, and we clear up when we are done.
Why act early in Lullingstone
A quick bead over the top of old mastic looks like an easy fix, but it will not grip old, dirty sealant. It peels before long, and water still gets in behind. Proper resealing starts with removing the old joint. Around Lullingstone, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.
