Just like our health, our houses need regular check ups. Property upkeep is more crucial than ever, with buyers reluctant to look at properties that will prove costly to patch up. ‘Properties that had fallen into disrepair captured a premium in boom years, when buyers wanted projects, but in these cash-strapped times, buyers prefer something that's been well cared for and isn't going to throw up unpleasant financial surprises,' explains James Greenwood from Stacks Property Search & Acquisition. What starts out as a quick £50 fix can descend into a £5,000 repair if left unattended. ‘Doing little jobs as they become necessary is the best advice I can offer,' Mr Greenwood adds.

Phil Spencer, presenter of Channel 4's Location, Location, Location, compares building maintenance to dealing with your health: ‘Prevention is always better than a cure. Regular maintenance of your home is less intrusive and expensive than letting it fall into decay and having to fix it.' A trained building surveyor, Mr Spencer regularly gets his hands dirty checking and repairing both his London home and his farmhouse in Kent. ‘At this time of the year, I clean out gutters, make sure drain holes are clear and use a cane to remove debris out of air bricks. I check chimneys as well, to ensure air is circulating around.'

Here are a few pointers for you to look for,

1. Do you have a chimney?

• is it leaning?

• is there any growth coming from the top?

• can you see mortar missing from the joints?

All of these can lead to potential problems

2. Check your roof covering

• if it's covered with tiles or slates, are any slipped or missing?

Look out for tile debris and pieces of tile lying on the ground-these can be tell-tale signs of problem areas, that will allow rain to enter and cause rot very quickly

3. Look at the ridge tiles along the top of your roof

• are they all there?

• are there gaps where they join each other or can you see daylight through the joints?

Check your tiles and slates. Gaps may indicate a need to repoint the ridge tiles

4. Check your gutters

• are they leaking at joints?

• do they overflow?

• are they catching water from the roof or is it running down the wall?

Looking at your gutters on a rainy day is the best way

5. Look behind the gutters

There are soffit and fascias, and, at the end of the roof, often barge boards. If they're made of timber, check if they need painting, as bare wood rots quickly

6. Are your rainwater pipes working?

l are they cracked?

l are they fixed securely?

l are they blocked with things such as leaves, twigs, tennis balls and even dead birds?

Check your gullies: green algae or vegetation on adjacent walls is a common sign that there is a problem

7. If your windows and doors are made of timber, they need painting every three to five years

• is there bare wood, especially on the sills and the lower parts of the opening sashes?

8. Look at the bottom of the rainwater pipes to check the gullies

• have they been regularly cleaned?

• are they working properly?

If not, they can cause dampness where the build-up enables water to penetrate a wall and, possibly, cause subsidence. Trim unruly foliage

9. Check all growth against the building, especially trees, bushes and ivy

• have you removed, cut back and pruned carefully where necessary?

These items growing on a wall can also cause dampness and structural damage.

Rectifying these possible hazards will be of immense benefit when you actually come to sell your home, its all about maximizing your asking price.
