East Lothian homeowners know better than most how punishing the weather can get, especially through autumn and winter. If your windows are older, you've probably noticed the draughts creeping in around the frames, condensation sitting between the glass panes, heating bills that never seem to come down, and locks that don't inspire much confidence.
Old Windows Causing Problems in East Lothian Homes
These aren't minor annoyances. Cold spots near windows make rooms uncomfortable, and damp caused by condensation can work its way into walls and frames over time. New double glazing windows address all of these issues in one go, and the difference inside your home is noticeable from day one.
Solving Draughts and Heat Loss
Single glazed windows or old double glazing that has lost its seal simply cannot hold heat the way modern units can. Today's double glazing uses two panes of glass with an insulating gas fill, usually argon, trapped between them. That gap acts as a thermal barrier, slowing the rate at which warmth escapes from your rooms.
Our uPVC and aluminium window frames are also fully sealed during installation, so there are no gaps around the edges where cold air can push through. Many customers in East Lothian tell us their radiators don't have to work as hard once the new windows are in, and rooms that used to feel cold in the evenings stay a lot more comfortable.
All of our double glazing windows are rated to A or A+ energy rating, which means they meet the current standards set out by BFRC. That rating matters if you're thinking about running costs over the years ahead.
Better Security for Your Home
Older window locks are easy to compromise, and many standard door locks offer less protection than homeowners realise. When you choose new windows and doors from Weatherseal, every product comes fitted with multi-point locking systems as standard. These lock at several points along the frame rather than just at the handle, making forced entry significantly harder.
Our double glazed units also use toughened or laminated safety glass options where appropriate. This type of glass resists impact and, if it does break, it doesn't shatter into sharp pieces in the way standard glass does. For ground floor windows and front doors especially, that matters.
Door security is something a lot of people overlook until something goes wrong. Our composite and uPVC doors come with anti-snap, anti-drill, and anti-pick cylinder locks, giving you solid protection without having to buy upgrades separately.
Dealing with Condensation Between the Panes
If you can see misting or water droplets forming between the two panes of your existing double glazing, the sealed unit has failed. Once that seal goes, the insulating gas escapes and moisture gets in. No amount of cleaning will fix it because the problem is inside the unit itself.
Replacing failed sealed units, or fitting entirely new windows, sorts this out properly. Our double glazing uses high quality warm edge spacer bars around the edge of each unit. These reduce the temperature difference at the edge of the glass, which is where condensation and cold bridging tend to start in the first place.
Internal condensation on the room side of the glass is usually a ventilation issue rather than a window fault, and our fitting team are happy to talk you through that when they visit. Getting the right advice early avoids unnecessary work later.
Our Fitting Team and How Long the Job Takes
Weatherseal's installers are experienced window fitters who work throughout East Lothian and the surrounding areas. Most standard window replacement jobs are completed within a day, even when several rooms are involved. Larger projects or full door and window installations across a whole property typically take two to three days. You won't be left with unfinished work or open frames overnight. Everything is made good before the team leaves each day, and all waste from the job is removed from your property.
Your 10 Year Guarantee
Every installation carried out by Weatherseal Windows And Doors comes backed by a 10 year guarantee covering both the products and the workmanship. That means if anything develops a fault with the frames, the sealed units, the locks, or the fitting itself within that period, we come back and put it right. No quibbling, no call centre queues. You deal with the same local company that fitted your windows in the first place. It's straightforward cover that gives you real confidence in the work.
