At Ignas Ltd., we’ve always believed that doing things the right way means doing them safely. That’s why we’re genuinely proud to share that we’ve once again earned the SafeContractor certification for 2025.
Over the years, working as painters and decorators in London, we’ve come across all sorts of exterior woodwork issues—some minor and easy to fix, others that require a full-scale replacement. Time and again, we’ve seen how rain, snow, strong sunlight, and fluctuating temperatures can wear down untreated wood. Even the sturdiest-looking frames can slowly succumb to cracks, rot, or a loss of insulation if they’re not properly protected.
From our perspective on countless projects, it’s clear that investing in regular maintenance is far more cost-effective than waiting until damage becomes too severe. If you let things slide, you may end up having to replace entire components, which is far pricier than a few coats of protective paint or varnish early on.
Common Threats to Exterior Wood
Based on our on-site experience, exterior woodwork is typically most vulnerable to:
- Prolonged UV Exposure
We’ve observed how intense sunlight can fade colours and weaken the wood’s structure surprisingly fast. - Temperature Swings
Extreme highs and lows cause wood to expand and contract, creating cracks over time. - Moisture and Rain
Water that soaks into fascias, sills, or cladding can lead to rot—one of the most common issues we’ve had to address. - Insects and Mould
We’ve seen firsthand how pests and fungi can undermine a building’s woodwork from the inside out.
The earlier we spot these problems, the easier (and cheaper) it is to deal with them. We always advise a proactive approach—don’t wait for minor wear to become major damage.
How We Check the Condition of Exterior Wood
Whenever we assess wooden frames and panels, we pay close attention to:
- Cracked Paint or Varnish
If the finish is flaking or peeling, the protective layer has likely lost its effectiveness. - Soft or Decaying Patches
We gently press or scrape to see if the wood has gone spongy or shows signs of mould. - Damaged Seals
Missing or broken seals around doors and windows often lead to draughts or leaks. - Moisture Build-Up
Fascias and soffits are notorious spots for dampness to set in—something we’ve learned the hard way on older properties.
A quick surface check can hide underlying issues. We often discover hidden rot or cracking only after scraping away a bit of paint.

Our Advice on Preventing Damage
From years on the job, here’s what we recommend to help you get ahead of woodwork problems:
- Regular Painting and Varnishing
A solid coat of paint or varnish acts as a first line of defence. We usually refresh these layers every few years to combat moisture and UV exposure. - Quality Wood Preservers
Not all products are created equal. Good preservatives deeply penetrate the wood and help ward off fungus and rot. - Tackle Small Cracks Early
We’ve seen tiny splits turn into major problems almost overnight—prompt repairs can save huge headaches down the road. - Routine Cleaning
Clearing away dirt, mould, and debris might seem minor, but it’s a big help in keeping moisture out. - Call in a Pro
Bringing in decorators in London every now and then for an inspection can uncover warning signs you might have missed.
Unsure If Your Woodwork Needs Work?
If you haven’t done any upkeep for a few years, it’s probably time to give your frames and panels a quick check. Sometimes a fresh coat of paint is all that’s needed; other times, more involved repairs are necessary. But in our experience, keeping up with regular maintenance extends the life of your exterior woodwork and preserves your property’s kerb appeal.
