Common questions in Widford
Is Widford within the area you cover?
Yes, Widford is covered. 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.
Can you help a landlord with a rental near Harlow Town station?
Yes. We work for landlords and agents as well as homeowners. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we will send you a clear quote.
Can you reach windows above the ground floor?
Yes, as long as they can be reached safely. Let us know about access when you ask for a quote and we will plan for it.
Can you seal the gap between the frame and the plaster indoors?
Yes. Plenty of draughts come through the inside joint as well as the outside, so it can be worth sealing both.
Do you have sealant for grey or black windows?
Yes, we choose a colour to suit the frame. Anthracite grey, black, brown and white cover most frames, with clear as an option.
Are you insured?
Yes. Full insurance covers our work.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you do not need to watch us work.
Will it make a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
About our window mastic in Widford
A cold draught around a closed window often comes from the frame edge. A new joint stops the air getting through. Where the air is getting in through the window itself, we’ll say so. If you are dealing with cold air getting in at the frame edge and draughty joints inside around the window, we can put it right, on composite doors, uPVC windows and patio & French doors alike.
Outdoor sealant needs dry, clean surfaces, so work on frames around Widford is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
A 12-month guarantee comes as standard.

How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Clean frames with a soft cloth and soapy water
- Avoid blasting the frames with a pressure washer
- Ventilate rooms so frames don’t stay wet inside
- Keep drainage slots and sill grooves clear
Keep the new mastic undisturbed while it cures, for as long as we advise. Keep jet washers away from the frames.
Water trapped behind a failed joint can start rot in timber frames and sills. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.
Can I do it myself?
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
How the job changes by surface
Composite doors
Composite doors are normally hung in an uPVC-type frame, and the joint around it is sealed like a window. The bead is colour-matched to the frame.
uPVC windows
uPVC expands and contracts noticeably with temperature, so the joint needs a low-modulus sealant that stays flexible. White is the usual colour, with brown, anthracite grey and black for coloured frames.
Frames and glazing around Widford
With historic houses such as Much Hadham Palace (about 2.6 miles north) nearby, there’s older building stock in the area around Widford 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. 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.
If you look after a building such as Widford School, its window and door frames need their mastic kept sound, just like a home’s. If you live in an older home near Parish Church of St John the Baptist, the joint between an old wall and a newer frame is normally the first place rain gets in. If you let a flat or house near Harlow Town station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

- How many joints, rooms or windows are involved

How the visit works
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a handful of frames, longer for a whole house. Somewhere as small as Widford, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely, along with any loose debris.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
How to prepare
- Keep children and pets away from the work area
- Try not to wet indoor joints just before the visit
- Let us know if you’ve seen damp or leaks
