Sand Mastic in Lordington
Problem with your window and door surrounds in Lordington? We cut out the old, prepare the joints and apply the right sealant.
- Mastic that needs renewing before redecorating
- Failed mastic on an exposed elevation
- Cement or filler used on old window joints that has cracked
Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
How we handle sand mastic in Lordington
If your home is listed or in a conservation area, check with your local planning authority if consent is needed before window work. Sand mastic is often favoured as a like-for-like material. We are often asked to deal with modern sealant on a period surround and old cement repairs round a window that have failed, across stone surrounds, brick reveals and tenement windows.
Homes in small places like Lordington often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

Your questions about sand mastic in Lordington
Is Lordington within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you work for landlords with property near Southbourne station?
Yes. We work for letting agents and landlords as well as householders, and several properties can be quoted together. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we’ll send you a clear quote.
Where do you work from?
We work from Crawley. Our applicators cover Lordington, along with the rest of our area.
Do you work for hotels and businesses?
Yes. We’ve worked for hotels, offices and other businesses, and we are fully insured.
What sealant do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
When will the new mastic be hard?
The surface skins quite quickly and it hardens fully over a longer time. The weather and joint depth both affect it.
Can you seal over the old sealant?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
What sealant work can’t fix
New sealant cannot fix everything, and we’d rather say so up front. It will not solve:
- Broken panes
- Sashes that rattle, stick or won’t open
- Decayed frames that need repair
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.

When to call us in Lordington
Decorating can disturb tired mastic. It’s often found when windows are being prepared for paint, which is a good time to renew it.
Common reasons people contact us include:
- Old cement repairs round a window that have failed
- Cracked mastic round a front door frame
- A silicone bead on a sash window that spoils the look
- Weathered mastic on the most exposed windows
For landlords with property near Southbourne station, older sash windows in a rental need their mastic kept sound to keep the weather out.
Questions to ask before booking
- How long the guarantee is
- What the cure time is
- Are they insured?
- Whether VAT is included
Aftercare tips
A little care helps the new joints last. We recommend:
- Plan mastic work ahead of painting
- Avoid heavy scraping on the mastic joint
- Keep sills and gutters clear so water drains away
- Get any rot dealt with first
Avoid painting over the new mastic, which is the traditional advice. If you are redecorating, ask us first.
Sound mastic protects the frame. Failed mastic lets water reach the timber and timber that stays wet can rot.

Related advice
Why act early in Lordington
Cement-based fillers and modern sealants don’t always suit a period surround. Sand mastic matches what was there, which can matter on listed and conservation-area homes. Older cottages and farmhouses around Lordington can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please ring 0345 464 0079 or drop us an email.

Frames and glazing around Lordington
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Warblington Castle (about 4.2 miles south-west) are a reminder that the area around Lordington has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Schools such as Bourne Community College are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. For an older house near a landmark such as Racton Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
