Sand mastic in Newenden, done properly
A silicone bead around a sash window can look out of place and isn’t always the right material. Sand mastic gives a finish that matches the age of the house and we can swap the silicone for it. We are often asked to deal with wind and rain getting in round a sash window and old sand mastic that has cracked, crumbled or fallen out, on tenement windows, timber door frames and sash and case windows.
Outdoor sealant needs dry, clean surfaces, so work on frames around Newenden is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
All of our work is guaranteed for twelve months, in Newenden and everywhere else we cover.

Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Look over the window mastic once a year
- Keep sills and gutters clear so water drains away
- Ask a joiner to look at soft timber first
- Sort the mastic before the decorators arrive
Avoid painting over the new mastic, as traditional guidance advises. Ask us before any decorating around it.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens.

Your questions about sand mastic in Newenden
What guarantee comes with sand mastic in Newenden?
Every job comes with our one-year guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Can you do sand mastic in Newenden?
Yes, Newenden is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll give you a clear price.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us.
Should I use sand mastic or silicone?
For period timber windows in stone or brick, sand mastic is often the better fit. On modern frames, we’d normally use a flexible sealant.
Can landlords and businesses book you?
Yes, regularly. Several properties can be quoted together, and between tenancies is a good time for the work.
Are you fully insured?
Yes. We’re fully insured.
Is it worth trying it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Can I choose the sealant colour?
Yes. White, clear and grey are common, and other colours are available, and we’ll agree it with you first.
When it is not the sealant
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Cracked or broken glass
- Rotten sashes, sills or window boxes (a joiner’s job)
- Damaged stone surrounds
If in doubt, phone 0345 464 0079 or email us and we will say what we think before you book.

How we quote for sand mastic
Jobs vary more than people expect. The main factors:
- The old material and how stubborn it is
- Access and height
- When we can work, for business premises
- Which sealant suits the joint
What you pay reflects the work, not guesswork. That’s why we ask about the job first.
What to tell us for a quote
Before you ask for a quote, have a think about:
- The rough size of the job
- The problem you’ve noticed
- If someone has resealed it before
- Where the property is
Asking for a quote is easy: tell us what needs doing and where, and roughly how big it is. Photos by email help us understand the job.
DIY versus a professional finish
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
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 does not work out, we can still put it right.
Different surfaces, different methods
Brick reveals
Gaps between frame and brick let in rain and draughts. Renewing the mastic closes it.
Timber door frames
Sand mastic is used round timber door frames too. The method is the same as for windows.
How it works
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself generally takes a few hours per window, depending on the condition of the joints, depending on how much there is to do. Somewhere as small as Newenden, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check each window surround and the condition of the joint.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic is not too thick.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Tell us about any water getting in
- Let us know about parking restrictions

Windows and doors in Newenden
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. Historic houses like Great Dixter (about 1.7 miles south-west) are a reminder that the area around Newenden has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
For an older house near a landmark such as Parish Church of St Peter, the joint between an old wall and a newer frame is normally the first place rain gets in. In and around Newenden, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.
