Default Basement waterproofing - need to find a contractor....

Well when I purchased this house I knew it had some water problems. This weekend I found out how bad. Several months ago I had a few basement waterproofing Co's in here for estimates. They all seemed to pull the 1 to 2 hour wife must be there BS. All perform the work on the inside. We have radon so that is another issue that comes into play. I'd like to find a company that will waterproof from the outside but cant seem to find any.

Can anyone recomend a good water proofing co that they have 1st hand experience with?

Anyone have any opnions on weather to get and inside system or have the work done on the outside? Anyone know a contractor that will do the work on the outside?

Suggest you investigate the concept before you graduate to the mechanics and, ultimately, to the providers.

....having work done from the inside out is (as you suspect) not the right way to do things because moisture is still wanting to penetrate the foundation walls. That's a constant that needs to be reversed.

...the source of water invasion is gravitational. Look up the slope and try to figure out a landscaping plan that will divert water from hitting the house and staying there.

...close-quarter battle lies in stuff that sits next to the foundation walls and collects water in order to divert it around the structure. Think French drain technology.

If you really want to seal the foundation wall, dig the trench and seal it from the outside with a thick tar-like substance. More expensive, but very well fixes the problem after you've done the diverting and draining.

Don't waterproof your interior until the exterior is dry or you trap moisture in earth and create a mildew environment.

I looked into this and here's what I had to do.

I needed just the rear foundation done, approx 50 feet. To do the job correctly on the outside the estimate was $24,000 dollars. This would have included; the dig, applying sealer to the foundation, applying the plastic protection sheet (more technical name I forget), some drains if I remember and of course back filling.

To do the inside sump pump remove cement, install stones, pipe and the plastic guide along the foundation was $7000k (still high). Guess which I had done.

The outside route if done by a legit company is building code issues as to how far out they have to dig for each foot down, so basically they were going down 6-8 feet and out about 4-5 feet, big hole. When they were done I would still have the landscaping issue and some sidewalks to replace $$.

I really wanted this done on the outside but couldn't justify the cost as this stage of my life in this house.

So far it has worked great, hurricane Irene did not give me one drop of water.

Good advice.

If water doesn't get to the house, it can't come in.

Are there gutters? (Extend the discharge at least 10' from house, underground in 4' corrugated with tee and grate at end)

Develop positive drainage away from house.

Use slotted corrugated and lots of pea gravel to collect and divert water to pea gravel pits. (Pump from there if need be)

Those interior systems simply collect water and pump it down a drain.

Your in Surf City, NJ and have a basement? The only Surf City I'm aware of is on LBI and I didn't think they had basements there.

My mom had a water problem on her home in Beach Haven West (Manahawkin waterfront) we had a company come by and install a french drain around the entire outside of the slab with the run off going into the lagoon. So far 4 yrs. it works great no water into the house that we can tell and with wall to wall carpeting you can tell pretty quick (it acts like a sponge). Let me know if this is the area in NJ your talking about and I'll see if I can get you the name of the company we used.

I used Healthy Home Basement Waterproofing out of Piscataway, NJ.

Doing the inside work they came in with a crew of about 8 guys and busted azz all day and were done by 6pm. This was an upside to me not having to take more time off from work.
