What the job involves on each surface
Sash and case windows
Most of our sand mastic work is on sash windows. We renew the mastic round each box.
Timber door frames
Period doors in stone or brick openings are often pointed with sand mastic. We renew it the same way as on windows.
How we handle sand mastic in East Wickham
Sand mastic does not last for ever, leaving gaps round the window. We rake it out and renew it so the surround looks right again. We work on brick reveals, timber door frames and stone surrounds, and people most often call us about open joints round the window box and mastic dropping out of the joint.
London has a lot of flats and conversions, where windows are often on upper floors. In a converted house or block, the lease usually says who is responsible for the windows, so it’s worth checking before booking, and access in East Wickham is something to talk through when you book.
Each job carries a 12-month guarantee.

Sand mastic in East Wickham: local notes

The process
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours per window, depending on the condition of the joints. In East Wickham, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- First, we look at the surrounds with you and agree what needs doing.
- We rake out the old mastic and clean the joint.
- We pack any deep gaps so the mastic sits at the right depth.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
How to prepare
- Mention if the joints have been sealed before
- Let us know about stairs, lifts or work at height
- Plan for the work area to be out of bounds to pets and children

FAQs for East Wickham
Is parking an issue for sand mastic in East Wickham?
Parking in East Wickham, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.
I let a flat near Welling station. Can you help?
Yes, we work for letting agents and landlords. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear price.
How do I get a quote for sand mastic in East Wickham?
Size, access and the old material all affect the cost. Call for a quick quote and we will talk you through it.
Will there be a smell?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
How long does sand mastic take to go off?
A skin forms quite soon, but full hardening takes longer. We will tell you what to expect for your job.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
Should I use sand mastic or silicone?
We will help you decide. Sand mastic suits many period homes, and modern sealants suit newer frames.
Will it make a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Should I try it myself first?
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
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, and the work is guaranteed for a year.
For landlords and businesses
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
We also work for property managers and facilities teams. Several sites can be quoted together.
Signs you need sand mastic in East Wickham
Timber frames move with the seasons. That movement opens up the mastic joint little by little.
Common reasons people contact us include:
- Wind and rain getting in round a sash window
- Mastic that needs renewing before redecorating
- Cracked mastic round a front door frame
- Mastic worn away on windows facing the weather
Rented homes near Welling station change hands often, and any sash windows need sound mastic to keep draughts and rain out.
Before you book anyone
- How much experience the applicator has
- Is the old sealant removed completely?
- What the quote includes, VAT included or not
- How the joint is cleaned and prepared
What happens if it’s left?
New mastic over crumbling mastic will not hold. Raking out and preparing the joint gives it a sound base so the new mastic stays put. In a flat in East Wickham, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we will go through it with you.

Aftercare tips
A little care helps the new joints last. Our advice:
- Avoid heavy scraping on the mastic joint
- Find out about consent before window work on a listed home
- Avoid patching sand mastic with silicone
- Ask us before painting near the mastic
Check the mastic when you check the paintwork. Catching cracks early keeps repairs small.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens.
