Water Intrusion Investigation & Repair
Let’s face it; water is the most critical substance to support the existence of life. That very element can be the worst enemy to the property owner. Weather related water damages, plumbing breaks and faulty appliance parts are just some of the things that can happen and there is never a good time for it. Murray Construction Services, Inc. can find it, solve it and put it all back together…the right way.

Leaking windows, failed siding and stucco, improper flashings…from the isolated incident to an entire development, Murray Construction Services, Inc. can help you with the problems the developer doesn’t want you to know about.

Building Defect Investigation & Repair
Unfortunately the construction defect is a common occurrence in new construction and is not obvious until years later after major damage has been done. Faulty workmanship, use of inferior materials, site planning, and engineering are just some of the things that can lead to hidden nightmares for the single family homeowner and the common interest development community.

Common Building Defects:
• Stairs and Landings
• Windows
• Patio Sliding Glass Doors
• Roofs
• T1-11 Siding and Stucco Systems
• Balconies
• Flashing and waterproofing Systems
• Foundations

Case Study:
Water Intrusion Investigation and IR Report.
The following investigation report is for water damage found at the master bathroom soffit over the toilet area. Initial inspection was performed using an infrared camera to produce a heat diagram or a visible image utilizing the infrared spectrum as a means of monitoring and diagnosing the condition of the building. A wet spot, when observed with an infrared camera, is visible in the following thermal images as a distinct dark or “cold” spot. Please note that because some surfaces are reflective and can give false readings, a non-penetrating moisture detector was used to back up our findings.

Master Bedroom/Bathroom Area
During our initial investigation visible water damaged sheetrock was present at the soffited area above the toilet. In the thermal image below, moisture saturation was found at the soffit and the upper left wall next to the toilet.

Second Floor Common Bath
During further investigation of the interiors, the second floor common bath toilet and window were found to be in close proximity of the master bedroom water damage. Based on the location in relation to the moisture saturated master bathroom soffit area, we suggested that water testing be performed to pinpoint the source of the intrusion at the flat roof to wall transition and the second floor common bath retrofit window.

Inspection and Water Test of Exterior Surfaces
On December 12, 2008 portions of drywall were removed from the soffit area to facilitate water testing of the flat roof. During the removal of the damaged drywall a leak was found at the solder joint of a 1” copper supply line. Water staining was noted above this supply line indicating a possible water intrusion from the exterior in addition to this plumbing leak.

Drywall was removed from the wall of the second floor common bath adjacent the flat roof to wall transition to facilitate water testing. Using a calibrated Monarch spray nozzle manufactured by Newton Tool Manufacturing to emulate heavy wind driven rain, water testing was performed at the roof to wall transition and window with no moisture penetration. However further inspection of the second story roof, also found to be in proximity of the master bathroom penetration point, we found that cracked stucco was present at the roof to wall corner transition, voids at the plumbing vent jacks and the raised fascia area directly above the moisture termination point of the master bathroom. During further water testing of the roof to wall corner of the second story roof, moisture penetration was found at the opened interior wall adjacent the toilet in the common bath. Penetration occurred within 10 minutes of saturation at the roof to wall corner.

In conclusion to finding two sources causing water damage to the soffited area of the master bathroom and the wall adjacent the toilet of the second floor common bath, we suggest that a licensed plumbing contractor repair the leaking copper supply within the soffit at the master bathroom as well as roofing repairs performed by a licensed roofing contractor to prevent further intrusion into the second floor common bath.

It is my professional opinion that the leaking pipe found within the soffit area of the master bathroom and water intrusion as a result of wind driven rain are both contributing to the water damage in the master bathroom.
