Winter Home Maintenance Checklist: 5 Essential Jobs Every Homeowner Should Do Before the Cold Sets In

Winter in the UK brings freezing temperatures, heavy rain, strong winds and damp, all of which can put a huge strain on your home. A few small maintenance jobs now can save you hundreds of pounds in repairs later, while also keeping your home warmer and more energy efficient.

Here are five essential winter home maintenance tasks every homeowner should tackle, and how the right building materials can make the job simple.

1. Clear & Protect Your Gutters

Blocked or overflowing gutters are one of the biggest causes of winter damp and roofline damage. When gutters fill up with leaves and moss, water has nowhere to go so it spills over, soaks into walls, damages fascias and can even cause leaks inside the house.

How to prepare your gutters for winter:

• Check for blockages and scoop out debris.

• Flush the gutter with water to ensure proper flow.

• Inspect for cracks or sections pulling away from the fascia.

• Install a gutter brush to keep leaves out for the rest of the season.

Products to use:

• Brett Martin guttering (robust PVC, perfect for repairs or replacements)

• Gutter brush for long-term protection

2. Seal Draughts Around Windows & Doors

Draughts are one of the biggest sources of heat loss in older properties, and even modern homes can develop small gaps and cracks over time. Sealing these areas is a quick, cost-effective way to keep your home warmer and reduce energy bills.

Where to check for draughts:

• Around window frames

• At the bottom and sides of external doors

• Where trims or architraves have pulled away

• Cracks between walls and frames

What you’ll need:

• Silicone sealant for sealing gaps

• Architrave or trim to cover larger or uneven gaps

• Application tools for a clean finish

Products to use:

• Trims & architraves

• Silicones & sealants

And if the issue is more than minor draughts for example, warped or rotten exterior doors, this may be the time to consider a replacement. We supply quality uPVC and Composite external doors, please contact us to enquire.

3. Touch Up Key Areas With Winter-Friendly Decorating Tools

Winter is a brilliant time to get small indoor decorating jobs done. While you may not be repainting whole rooms, touching up scuffs, filling cracks and refreshing trims before damp weather arrives can make a huge difference.

Popular winter maintenance tasks:

• Filling cracks around window sills

• Touching up high-traffic areas

• Refreshing sealant lines that have cracked

• Smoothing or sanding damaged areas

• Applying new trims where old ones have warped

Since you supply tools rather than paints, this section can focus on surface preparation, which homeowners often neglect.

Products to use:

• Fillers, caulking guns, sealants

• Scrapers and sanding tools

• Decorating accessories

4. Check Your Roof Line and Surrounding Areas

Winter storms can expose any weak spots in your roof, and simple checks now can prevent leaks later.

What to look for:

• Loose or slipped tiles (visible from ground level)

• Missing ridge or hip mortar

• Damaged fascias or soffits

• Moss build-up around roof edges

• Overflowing gutters or water trails down walls

If you notice any minor gaps in the roofline trim or around joints, silicone sealant can temporarily prevent water ingress until repairs can be made professionally.

Products to use:

• Silicones & sealants

• Guttering replacements (if damaged sections are found)

5. Upgrade Key Areas to Prevent Damp & Improve Insulation

If your home struggles with cold spots or recurring damp, winter might be the right time to upgrade certain elements.

Possible upgrades:

• External doors that have bowed, swollen or become inefficient

• Window frames that no longer seal properly

• PVC-U skirting (like Deeplas Roomline) which is moisture-resistant and ideal for preventing mould in colder rooms

• New trims to tidy up and seal problem areas

Products to use:

• Deeplas Roomline skirting (perfect for bathrooms, kitchens, utility rooms)

• External doors (available by enquiry)

• Trims & sealants for a clean, insulated finish

Final Thoughts

Winter maintenance doesn’t need to be a huge job, it’s often the small tasks that make the biggest difference. By clearing gutters, sealing gaps, refreshing key areas and inspecting your roofline, you’ll protect your home from damp, improve heat retention and avoid costly repairs.
