Q: Is water coming up from the floor an emergency?

• <div><p>Yes, water coming up from the floor should be treated as an emergency.

Q: Does water damage always result in mold?

• <div><p>Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. The chances of mold developing depend on several factors, including the severity of the damage and how quickly the area is cleaned and dried. To prevent mold, you must act quickly&mdash;ideally within the first 24 hours. Clean up all water and thoroughly dry the affected area. If the damage is extensive, you were unable to address it immediately, or you suspect mold has already started to grow, it is best to assume it is present and hire a professional mold inspector or removal expert to assess the situation.</p></div>

Q: Can I add a sump pump to an existing basement?

• <div><p>A sump pump can be added to an existing basement. To do this, you will need to use a jackhammer or sledgehammer to break up the concrete and dig a pit. You will also need to create a hole in your basement wall to run the discharge pipe through.</p></div>

"My old water heater went out yesterday and of course leaked water all over. I shut it off and stopped the leaking. Called early this morning looking for someone to install a new one. Jim was actually sent over by another plumber who could not get to my job right away. Jim showed up, looked at the job, we talked about the options and he gave me a bid. Let to get the new water heater. We back in about thirty minutes. He had to make some changes to the water and gas lines. Added shut offs and installed new one. Took the time to explain operation and maintenance of the new one. Cleaned up the work site. Removed all debris and old water heater. I was impressed with his work and his attitude.

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.

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.
