About our sand mastic in Turnford
Sand mastic suits most period window surrounds. Newer frames normally get a flexible sealant instead and we’ll explain which is best for yours. We work on brick reveals, sash and case windows and tenement windows, and the jobs we see most are old sand mastic that has cracked, crumbled or fallen out and silicone on a period window that looks wrong.
Many houses in smaller places like Turnford have conservatories, garden rooms or patio doors. Their glazing joints and frame seals are as much a part of the job as the windows.
A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

FAQs for Turnford
Can you do sand mastic in Turnford?
Yes. Our work covers London and the South East, and Turnford is part of that. You can phone 0345 464 0079 or send us an email and let us know what needs doing.
Is Turnford within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Are you ARBOMaster approved?
Yes. We are approved under the ARBOMaster scheme.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Are you insured?
Yes. We are fully insured, with over 20 years’ experience in sealant work.
Is it OK to seal over old sealant?
No. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Do you offer different sealant colours?
We help you choose a colour that suits. The product needed can limit the range.
Do I have to be there?
It depends on the job. For work indoors, someone needs to let us in.
Can I do it myself?
If you’re 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.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Aftercare tips
A little care helps the new joints last. Our advice:
- Make sure water runs off the sill
- Go gently near the mastic when preparing windows
- Renew mastic before redecorating the windows
- Ask the planning authority about consent for listed or conservation-area homes
Leave the new mastic alone while it firms up. It skins over quickly but needs longer to fully harden.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens as more mastic falls out.

Surfaces we seal
- Sash and case windows
- Stone surrounds
- Brick reveals
- Period & listed homes
- Timber door frames
- Tenement windows
Different surfaces, different methods
Timber door frames
Door frames get knocked and soaked, so their mastic can fail sooner. We rake it out and renew it.
Sash and case windows
Most of our sand mastic work is on sash windows. We renew the mastic round each box.
Windows and doors in Turnford
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Forty Hall (about 4 miles south-west) nearby, there’s older building stock in the area around Turnford 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.
For an older house near a landmark such as St Clement, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Rented homes near Cheshunt station change hands often, and any sash windows need sound mastic to keep draughts and rain out. For site and facilities teams at buildings such as Longlands Primary School and Nursery, its window and door frames need their mastic kept sound, just like a home’s.

How the visit works
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours for a single window, longer for several and we leave things clean and tidy. Parking around Turnford is usually easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- We start by checking each surround and agreeing the joints to renew.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The mastic is finished to sit tidily against the stone or brick.
Before we arrive
- Mention if the joints have been sealed before
- Let us know if you’ve seen damp or leaks
- Try not to wet indoor joints just before the visit

Advice
Why it’s worth doing now in Turnford
Not every filler suits an old window surround. Sand mastic is the like-for-like choice, which can matter on listed and conservation-area homes. In a smaller place like Turnford, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
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.
