in 10 years of business, we have come to find several common mistakes made by homeowners that can ruin a deck. here are 5 things to avoid to keep your deck looking beautiful allowing metal items such as furniture or planters to remain wet for long periods of time on your deck will cause rust stains to occur.
nothing in your garden, including decking, which is up against the house, should be any higher than 150mm below the damp proof course. the damp proof course is there to stop water soaking up the bricks and getting into your house, if you place things against the wall which will allow the rain to splash against the wall above the dpc it can soon soak the wall and lead to damp indoors.
the deck is older but has been sanded, stained and sealed recently. i would like to place a colorful outdoor rug under the table and chairs but i'm concerned that the decking will be wet/moist underneath the rug and rot the decking. i couldn't find any information on this issue.
rising damp usually occurs in masonry walls because of the failure or absence of a damp-proof course, although poor sub-floor ventilation and bad site drainage can also be contributors.
last year one of my daughters bought a split level house built on a slope - one side of the house is decked feet above the dpc and it wasn't mentioned on the very detailed survey. they did comment that the dpc was above ground level and they couldn't tell if the supports for the decking itself were built on a damp-proof membrane.
if youve left your decking maintenance for too long you might find the boards have warped, something that happens when the deck hasnt been adequately weather treated. it can also occur when the weather has been particularly bad. whatever the reason, when your decking boards begin to warp and bow, you need to take action.
allowing metal items such as furniture or planters to remain wet for long periods of time on your deck will cause rust stains to occur. if the stains penetrate the decking too deeply, they may prove nearly impossible to remove.
the rotten decking was only in certain areas of the roof and only less than 10% of the decking. i wouldn't say the 10% replacement was due to roofing in wet conditions. that is my experiences
installing decking above the damp course. as the section of decking in question is only a thin strip, on a completely solid concrete base is it feasible to make it free standing. i'm confident i could seure it; but would it cause damp problems if the decking was installed above the dpc; even if it didn't actually connect to the wall at all
and last but not least, the roof deck system. although rare and unlikely, deck failures can occur. deck failures can be caused by excessive weight, typically as a result of the weight associated with standing water. decking failures can also occur as the result of storm damage from high winds. roof decks can deteriorate over time leading to failures.
building a deck above the dpc might cause you problems in the future and that is why it is recommended that you build the deck below the dpc and not above it. building the deck above or level with the dpc means that rain water can splash up and give you damp problems in the future.
decking above damp proof course. i do not think i will be able to fix the ledger board below the dpc as best practise. will it be ok to use spacer washers behind the ledger board allowing water run off. does anyone have any tips or is it really best not to breach the dpc? your help will be much appreciated. cheers russ.
decking basics. in reality this is often ignored, but the level of the deck must never be higher than the damp proof course. the decking structure should not be fastened directly to the fabric of the house, there should be at least a 10mm gap between the structure and the house.
rain-exposed wooden decks: 5 dos and donts. water seepage into your deck can cause considerable warping, but acidic elements in our rainwater can actually break down a wooden deck from within. nadra recommends staining immediately after power washing. - do: use a simple pump sprayer like this to apply your stain.
the hope is that it will hold up better and protect against moisture like a stain, but cover the surface more like a paint -- and not show the few remaining bits of old paint, as i was time-constrained in the removal, as well. but still, the wood is kind of damp.
any decking can get leaves underneath, but is your point that having the deck below the air vents is the most important thing? the stone patio below would need completely re-doing to make it level enough to have a lower deck on top of it
damp will be become a problem if there is a constant supply of water to a location. this is achieved by a break in the dpc or a supply above the dpc. supplies above the dpc are sourced from piles of **** in contact with the ground which go above the dpc and then soak into the wall. or other constant sources of water which arrive above the dpc.
issue the causes of damp floor problems can vary depending on the severity of the problem e.g. the floor may be slightly moist to the touch or you may literally have a puddle of water. a good place to start in establishing a cause is to inspect the outside of your property, your dpc and also any properties surrounding you.
can you have a chat with him along the lines of your garage wall is getting damp, can you have a builder come into his garden and have a look at it? if he'll co-operate with getting the damp sorted, especially if his decking is causing it, then the hanging baskets are a small price to pay?
