Landlord and commercial work in Mount Pleasant
In hotels, rooms out of use cost money, so we plan the work room by room. We’ve worked in hotels as well as homes and businesses.
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
How the visit works
We keep the work tidy and contained to the joints we’re treating, so you can get on with your day. Expect the work to take a few hours for a few frames, or a day or more for a whole house. In a small place like Mount Pleasant, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Let us know if you’ve seen damp or leaks
- Keep children and pets away from the work area
Getting a quote
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add photos by email if you can.

What sealant work can’t fix
Sealant is not the answer to every problem, and we’d rather say so up front. It won’t solve:
- Draughts through the window seals rather than the frame
- Broken hinges, locks or handles
- A failed sealed unit that has misted up
Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly before booking.
Surfaces we seal
- Window sills
- Timber windows & doors
- Composite doors
- Patio & French doors
- uPVC windows
- Aluminium frames
FAQs for Mount Pleasant
Is Mount Pleasant in your area for window mastic?
Yes, Mount Pleasant is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or email us with a few details of the job.
Do you cover smaller places like Mount Pleasant?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
How long should I leave it?
Cure times vary by product and the conditions. We tell you how long to leave it before we go.
I’m a tenant. Can you help?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
Will resealing my frames help with draughts?
Often, yes. The gap between frame and wall is a common source of draughts, and sealing the inside and outside joints closes that path.
Is there any odour?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.

How the job changes by surface
Aluminium frames
Aluminium needs a sealant that bonds to coated metal and we avoid acetoxy silicones, which can react with some metals. We use a neutral-cure product.
Window sills
The end joints of a sill tend to fail before the rest. A tight seal at each end keeps rain out of the wall.
Looking after it afterwards
After the cure time, these simple habits help:
- Wipe condensation off the frames
- Keep drainage slots and sill grooves clear
- Don’t paint over the silicone
- Repaint timber before it’s bare
Timber frames need their paint kept up, since wood that gets wet swells and shrinks more. Paint up to the joint, not over the silicone.
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. Catching it early keeps the fix to a reseal.
Windows and doors in Mount Pleasant
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.
Rented homes near Stansted Mountfitchet station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints. Schools such as Manuden Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. Homes close to Church of St Mary the Virgin include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in.
