Can I do it myself?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Window mastic in North Camp
A cold draught around a closed window often comes from the frame edge. Resealing that joint can make a room feel noticeably less draughty and quietens the whistle on windy days. Where the air is getting in through the window itself, we will say so. We work on timber windows & doors, uPVC windows and window sills, and common reasons people get in touch are mastic that has split away from the wall and gaps left after new windows were fitted.
Around North Camp, conservatories, garden rooms and patio doors are often part of the house. Their glazing joints and frame seals are as much a part of the job as the windows.
Each job carries a 12-month guarantee.

What we are called out for in North Camp
Some failures date back to when the windows were fitted. Sealant run over dust, wet brick or loose mortar never bonded as it should, and it lets go sooner than it should.
Signs it’s time to call us include:
- Cold air getting in at the frame edge
- Gaps between the frame and the inside reveal
- White mastic on grey or black frames
- Mastic that is falling out in pieces
In the older streets around St Mark, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
What your quote should include
- What happens if they find a problem under the old sealant
- How long the guarantee is
- Is the old sealant removed completely?
- Whether they’re fully insured
Landlord and commercial work in North Camp
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.
Why deal with it now?
Redecorating is a good moment to renew the mastic. A clean new bead makes new paint or render look finished, and it’s easier while the walls are being worked on anyway. Homes in smaller places like North Camp can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Why choose Mr Mastic in North Camp
- White, clear, grey or another colour, product permitting
- ARBOMaster approved applicator
- Tidy, careful work
- A sealant colour to suit the surroundings

What we do, step by step
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes most of a day for a typical house, less for a few frames and we leave things clean and tidy. For a job in North Camp, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- 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.
Before we arrive
- Mention if the joints have been sealed before
- Let us know about parking restrictions
- Let us know about stairs, lifts or work at height

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Use gentle cleaners on frames and sealant
- Don’t paint over the silicone
- Check the mastic once a year
- Keep drainage slots and sill grooves clear
Keep the new mastic undisturbed while it cures, following the cure time we give you. Keep jet washers away from the frames.
A failed joint lets water into the wall a little at a time. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.

Windows and doors in North Camp
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. With historic houses such as Farnham Castle (about 4.8 miles south-west) nearby, there’s older building stock in the area around North Camp 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.
Letting a property close to North Camp station? Then 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 St Mark's Church of England Aided Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
