Over the past few weeks, the Rochester area has experienced a staggering amount of continuous rainfall over a few day stretch. We have all seen the destruction that 6+ inches of rain, in hours, did in the Penn Yan area, but those situations are few and far between.
The average homeowner in a climate like ours (semi-frequent bouts of steady, continuous, multi-day rainfall) in Western New York, does get the occasional occurrence of clear water in the basement. It’s a fact of life, especially if you live in a flood prone area or have an older home built before the days of poured concrete and waterproofing of foundations. But there are things you as a homeowner can do that can limit or potentially eliminate water or moisture from taking over your basement. There are various levels of costs and effectiveness, but these can give you an idea of just some of the steps you can take:
- Keep water away in the first place! Make sure the grade outside is pitching away from the foundation and the gutter downspouts are extended away from the foundation as well. If you have hose bibs install a “splash block” under the hose connection to help prevent leaking water from digging a hole and letting the water find its way into the basement.
- Drylok the exterior walls. Drylock has been around since the 50’s, and it’s still one of the most effective ways to help prevent moisture from creeping in through the pores of your foundation. Prep your walls by scraping any decayed portions with a metal scraper, and removing any chipped or old paint. Spray a mixture of muriatic acid (wear gloves, a mask, and eye protection!) to kill any mold and mildew. Apply your first coat generously with a sturdy nylon-bristled brush (this part is painful and slow) and then apply a second coat with a thick knap (3/4″) roller. This stuff will last you years and it’ll really help keep the moisture out. Just make sure to ventilate your work area well while applying, it can get quite pungent. This can be done in a weekend, or even a day if you find a friend!
- Run a dehumidifier! While a dehumidifier will not prevent a “flooded” basement, it will help in lowering the consistent moisture that builds up along your cold foundation walls during the summer. Ever had a cold drink condensate on a hot summer day? That’s essentially the exact same thing that happens on your basement walls in the summer. This should be considered a MUST for most readers that have an older home (pre 1950 or so), don’t have air conditioning, or frequently experience that musty, stale smell. Set it for 50% humidity in the summer. We also recommend connecting a hose directly from the dehumidifier to the sump crock so that you don’t have to worry about emptying the reservoir. **Added benefit** – Most dehumidifiers have an exhaust fan. Tape a few dryer sheets or a car air freshener that clips onto the vents here, and you’ll instantly make it smell better!
- Add a sump pump. This is suggested for those that frequently experience moderate or significant basement flooding. Many old homes were built with “slab” basements. They have the edges or gutters along the outside edges and walls that slope down to a drain at the lowest point of the basement. This was the pre-sump pump way to combat flooding. Sump pump costs can add up (to over $1000), but they are very effective at siphoning water out of your basement and outdoors. Contact your trusted plumber for information to see if you could benefit from a sump pump.
A moist, wet environment can lead to the growth of mold, fungus, attract insects and rodents, and lead to premature decay of your foundation, wood structure, and more. Anything you do to eliminate moisture will be helpful in the long run.
