"Al and James completed my annual maintenance yesterday and they were very professional. They fixed some plumbing issues on my sump pump and fortified the sump pump outlet piping to prevent possible further issues. They also took special care to replace and improved upon the original floor linear over the sump pump and left the crawl space spotless."

"The owner (Michel Bervaldi) was very informative and forthcoming re the project. Unfortunately, financial priorities did not allow us to follow though without the project. We did speak with other contractors and Michel would have been our first choice if we were to proceed as originally planned."

"James and Robert came out early the next morning, after I had a huge leak under my sink and flooded kitchen. I called James at 9pm that evening. They arrived early to assess the problem and gave me an incredibly reasonable estimate. They are professional, friendly, and completed the repairs in record time. I live in a 65 year-old home and have had my share of inept, incompetent trades people, specifically plumbers, rip me off and do shoddy workâ ¦ James and Robert are top-notch, and even gave me good advice as to who to call to avoid a mold issue with the wet interior and exterior walls. Donâ t hesitate to call VIP Plumbing for your plumbing needs. They are awesome!!! Susan VanDenBerg"

"Great people and honest. I appreciate this all the more lately after having to deal with two separate plumbing companies who were not nearly as honest. They mounted a toilet, roughed in two drains and some other work for $306. I was quoted by another company that this job would cost almost $2000.   Honest people need to be rewarded and it is hard to find them these days. Thank you! Thanks again for helping me out:)"

Basement Waterproofing FAQs, answered by experts

To ensure your basement walls are waterproof, it's crucial to address any existing moisture issues before finishing. Inspect for signs of water seepage, such as dampness or discoloration, and repair any leaks or cracks. Install a vapor barrier to prevent moisture from penetrating the walls, and consider waterproofing paints or coatings.

Proper drainage systems, such as interior or exterior waterproofing, can also be beneficial.

Whether to waterproof your basement from the interior or exterior depends on several factors, including your budget.

Exterior waterproofing is generally considered the superior method because it stops water at the source, preventing it from seeping into and damaging your basement walls. This approach offers the most protection, making it ideal if you use your basement for storage.

By contrast, interior waterproofing is often less expensive and requires less labor because the area is more accessible.

For maximum protection against water leakage and moisture, applying waterproofing measures to both the inside and outside is the best solution. However, if you must choose only one, stopping water from the outside is the most effective approach to preserve your foundation and prevent damage.

When considering finishing your basement, take into account a few pros and cons:

Pros

  • Can increase the value of your home

  • Separate space from the rest of the house 

  • Customize and personalize the basement to suit your needs and style

  • Increase the amount of living space in your home

Cons

  • May not regain enough value to cover the cost of finishing

  • Lack of natural light if it’s below ground level

  • Moisture or flooding can cause costly damage

  • Installing plumbing and electrical can be messy and costly

Crawl space encapsulation typically lasts between 10 to 20 years. If you experience a catastrophic event, like a flood, or poorly encapsulate your space with low-quality materials, it may only last a decade. Otherwise, as long as you properly maintain your crawl space, a high-quality encapsulation can last more than 20 years.

In most cases, a crawl space will not dry out on its own unless the moisture comes from an uncommon flood and isn’t expected to be a recurring issue. For most homeowners, moisture problems in the crawl space will only continue to get worse over time, so addressing the underlying problem with gutter systems or a foundation drainage system and setting up a preventative solution like a dehumidifier is necessary.
