Basement in London with damp issues - what to do?

4 years ago

Hey all, I recently purchased a basement flat in London, roughly 45 sqm, and it's got mould, rot, and damp in the walls. Particularly bad on external walls, kitchen walls, and bathroom.

First round of builders suggested tanking the place, but my next door neighbour, whose flat is virtually the same as mine (and who had the same issues when she purchased), didn't go for the tanking and only applied damp proof paint. It's been 3 years and I can see no signs of damp/mould in her place.

We are not so sure on the tanking now, mostly because it's looking to add £10k to the construction bill, and if the damp proof paint is enough, why go all that extra distance?

Does anyone have experience with waterproofing basements or with basement conversions? Any advice would be appreciated!

Hi Zi,

Without a survey it is difficult to say if the paint would work for you in the same way as your neighbour. It may be that she has extra block work inside that acts as a barrier to any leaks which your side may not have. I understand why you would want to go for the more cost effective option, but best to get a damp survey to be sure and save paying for works that may fail in the short term.

Hi Zi,

are you sure that it is rising damp and not a result of condensation caused from moisture trapped in the room from inadequate ventilation. rising damp generally does not rise above 3ft and may display tide marks or pattern stains on walls.

it may be worth getting a damp specialist in to check it out. Paint treatment will not prove a long terms fix and depending on what improvements you plan to make in the future - it is best to resolve problems that put a sticking plaster on the problem.

If you want custom cream panelling built from scratch, it is likely to take you more than three weeks to line up a contractor, get it built and then painted. If you want to use beadboard (thin, lightweight, cheap) you can do it yourself if you are good at the small precision cuts around the wood window trim and behind the radiators. You can get a custom built wood cover with doors for your tv or use the painting over tv disguise made with hinges. I think the room is beautiful as it is. Spend some money on a truly beautiful, impressive chandelier, have it centered over the table. If you want to impress relatives at an event, the chandelier is the way to go. Clean the windows for extra sparkle. If you are in the US, try Home Decorators http://www.homedecorators.com for DVD storage cabinets that are closed. I would not get a rug for this room unless I was ready to get it cleaned frequently and I could find one that looked good with dog hair on it and did not show stains. A good quality, highly patterned wool Oriental rug will do that job nicely. Such a rug is an investment and may take longer than three weeks to find.

Wooden floors in the kitchen??
Q

I have to join this discussion of Hardwood in the kitchen. I am a little biased in this discussion because of being a tile contractor for almost 30 years. I have seen alot of hardwood kitchen floors. I have to give you the cons of putting hardwood in. Hardwood floors look great. As far as durability I am not sold. Hardwood floors look great when they are first put in. Depending on the traffic in the kitchen I give them about 4 to 5 years is when you see significant wear. I have seen alot of hardwood floors in kitchens with water damage. Now I know you think you wont have a leak from your dishwasher, refrigerator or a general plumbing leak. Well these things do happen and when it does the hardwood needs to be totally removed. Some times this is not so easy if the hardwood goes under the base cabinets. I am not saying do not put hardwood in the kitchen I think you should look at whats going to work for you. There are plenty of porcelain tiles that will give you the look of hardwood but give you the durability of a porcelain tile. Tile installed properly will last a long time. Hardwood will last but it will look warn to the point that it would need to be refinished at a cost around $2000.00 depending on the size of the room. I don't want to upset the hardwood floor lovers I have it all over my house except the bathrooms and kitchen. The floor is 20 years old 4 kids 2 dogs and still looks great. I am sure what ever you choose it will look great.

Put in a few French drains where you dig a ditch and fill it with crushed rock to help the water drain. In low spots put in some drains [http://www.homedepot.com/p/Tuf-Tite-16-in-2-Hole-Drain-Sump-with-Grate-and-Seals-2HDS-4/203463511] with pipe running to the French drain. You might also need to bring in 10 yards of top soil along with some sand to raise your yard a bit as you're probably right at the water table level. We've had to do all this as we live in the Pacific Northwest in a reclaimed marsh [a nice word for a swamp] where we hit the water table if we dig down 3". We had to put down about 10 yards of top soil along with some sand to raise our back yard. We also dug a French drain along the back to connect to the associations drainage pipes through the neighborhood. My husband has put in at least 3 of the drains in strategic locations around the yard to help drain off the excess water. Our yard isn't perfect, but it isn't the swamp it was the first couple of years we were here. We have to apply moss killer every spring or it takes over the yard. My husband also puts down lime to soften the soil, and help the water drain easier. He and a friend rent an aerator every summer and do both our yards to help with the drainage as well.

Should I paint the floor boards white?
Q
Comments (17)
It looks very pretty. I would look at pics of painted floors versus whitewashed and see which you prefer then people can hopefully help with methods. I've used chalk paint but not on a floor. Annie Sloan sell floor lacquer so you don't need to use the wax which is very time consuming to apply, the lacquer can be rollered on. The only thing I would say is that it does not adhere to I think varnish made in the 80's and I find the White paint coverage is poor although not an issue if white washing. I wondered if there was a cheat method using zinsser to avoid sanding if using normal paint and have found this, no idea on how successful it is! http://www.zinsseruk.com/how-to-guide/how-to-paint-woodstained-or-varnished-surfaces/
