Window mastic in Dartford, done properly
From a single sill to a whole house of windows, the work is priced before anything is done. Just ring 0345 464 0079 or email us and tell us how many frames there are and how they’re reached for window mastic in Dartford. We work on patio & French doors, timber windows & doors and aluminium frames, and people most often call us about whistling draughts around closed windows and mastic that has split away from the wall.
Dartford mixes older streets, where windows have often been replaced, with newer estates fitted with uPVC. In every case, the joint between frame and wall is what keeps water out.
Our work is backed for twelve months, and the guarantee is the same wherever you are.
What affects the cost of window mastic
For a quick quote, just ask. What matters most is:
- Working hours on commercial sites
- Whether old sealant or filler has to be cut out
- Mould in or behind the old joints
- The product the joint needs
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
Asking for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- If someone has resealed it before
- Roughly how big the job is
- If it’s domestic, commercial or a hotel
- The problem you’ve noticed
Call for a quick quote, or send an email if you’d rather. Tell us about the joints that need doing and we will talk you through the work before giving you a price.

Dartford homes and the weather
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Hall Place and Gardens (about 2.8 miles west) nearby, there’s older building stock in the area around Dartford 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 landlords with property near Dartford station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. For site and facilities teams at buildings such as Dartford Primary Academy, larger buildings have plenty of frames, and the mastic around each one ages.

Can I do it myself?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
What the job involves on each surface
Window sills
Sills catch the water running down the glass, so the sill ends and the joint under the frame are vital. They’re cut out and resealed with exterior sealant.
Composite doors
A composite door usually sits in a plastic outer frame, so its perimeter joint is sealed much like a window. We match the colour to the frame.
For landlords and businesses
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
If you manage several properties in or around Dartford, jobs at different addresses can go on one quote. Send us the addresses and the work at each.
The process
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself normally takes a morning for a couple of windows and a door, depending on the size of the job. Parking in a town like Dartford is generally straightforward, but tell us if there’s a driveway or any restrictions, and mention if the work is upstairs, in a flat or high on the outside.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
Preparing for the visit
- Mention if the joints have been sealed before
- Mention any parking rules near the property
- Mention any tricky access

Why it’s worth doing now in Dartford
Redecorating is a good moment to renew the mastic. A clean new bead makes new paint or render look finished. In Dartford, as anywhere, most leaks start as a small gap in a joint, and early is when they’re cheapest and quickest to sort.
Doing several joints on one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. We will give you a clear price for the lot.
Why Dartford clients choose us
- Old sealant always removed completely
- 20+ years of sealant experience

What we are called out for in Dartford
Sun, frost and rain wear sealant out. Sunlight dries the surface out, until it loses its stretch and starts to crack.
Look out for these signs:
- Rushed sealant from a window installation
- Draughts coming in around windows and doors
- Rain getting in at the frame or under the sill
- Cracked sealant at the sill ends
Homes close to Church of the Holy Trinity include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Questions to ask before booking
- Whether they seal over old material or remove it
- The length of the guarantee
- Whether they’re fully insured
- How the surfaces are prepared before sealing
