Leak Detection & Repair on Philadelphia's Main Line
The Dr. Leaks Main Line team knows how to diagnose, treat and repair leaks in historic homes and estates as well as homes with custom construction and unique roofing materials. We've got you covered!
Expert Leak Detection and Repair for Main Line Homes & Properties
When you have a mysterious water leak, moisture problem, or recurring water damage, finding the true source is often more difficult than fixing the visible damage. Dr. Leaks provides professional leak detection and repair throughout Philadelphia’s Main Line – from historic estates and stone homes to newer construction, Main Line properties can present unique challenges when it comes to water intrusion. Roofs, flashing, windows, masonry, plumbing, foundations, bathrooms, and building-envelope components can all contribute to a leak — and the location where you see water isn’t necessarily where the leak begins.
That’s where Dr. Leaks comes in. Our leak detection specialists look beyond the obvious symptoms to identify the root cause of your water problem. We then develop a detailed repair plan and can handle the necessary repairs and cosmetic restoration to help return your home to its original condition.
If you need leak detection or leak repair on the Philadelphia Main Line, Dr. Leaks can find the problem and help fix it for good.

Leak Detection & Repair Services for Main Line Properties
Dr. Leaks provides comprehensive leak detection and repair services for homes and properties throughout the Philadelphia Main Line, including:
Roof Leak Detection & Repair
Roof leaks can be difficult to locate, particularly when water travels beneath roofing materials before entering the home. Our specialists investigate the source of roof and exterior water intrusion and develop an appropriate repair plan.
Window & Door Leak Detection
Water around a window or exterior door doesn’t always mean the window itself is defective. Problems with flashing, surrounding masonry, seals, drainage, or areas above the opening can allow water to enter the home. We investigate the entire area to identify the actual source.
Plumbing & Pipe Leak Detection
Hidden plumbing leaks can cause significant damage before they become obvious. Dr. Leaks can investigate water problems involving pipes, fixtures, bathrooms, kitchens, and other areas of the home.
Basement & Foundation Leaks
Water entering a basement or lower level can originate from foundation walls, masonry, drainage systems, plumbing, exterior water intrusion, or other sources. We investigate the conditions contributing to the moisture problem rather than simply addressing the visible water.
Masonry & Building Envelope Leaks
Many Main Line homes feature brick, stone, stucco, and other exterior materials that require specialized attention when water gets behind the building envelope. We investigate masonry and exterior water intrusion to determine where water is entering and how it is traveling.
Ceiling & Interior Water Leaks
A ceiling stain or damp wall can be the first indication of a much larger problem. We trace visible water damage back toward its source and develop a plan to address both the leak and resulting damage.

One Company for Comprehensive Leak Detection thru Full Home Restoration on the Main Line
One of the biggest frustrations homeowners experience with a difficult leak is being sent from contractor to contractor.
A roofer may determine that the roof isn’t the source. A plumber may determine that the plumbing isn’t responsible. Our team has expertise across roofing, plumbing, waterproofing, masonry, windows, foundations, and building-envelope water intrusion. This allows us to investigate the complete problem rather than looking at only one potential source.
Once the source is identified, we provide documentation of our findings, including photographs and information about the recommended repair. With your approval, our team can complete the necessary work and, when appropriate, address the resulting cosmetic damage as well.
You don’t have to coordinate a parade of contractors just to figure out where your leak is coming from – one call, one contractor. Call Dr. Leaks for any issue on the Main Line.

FAQs
That is exactly what we are here for! Mystery leaks frustrate many homeowners, but our team brings decades of combined experience to every job. We specialize in comprehensive Leak Detection services to pinpoint hidden moisture sources. No matter where the water hides or what causes it, our specialists will find it, and fix it, for good.
Place a bucket to contain the drip, move furniture and rugs away from the area to prevent water damage, and set up a fan to dry any dampness. Read our guide for more information on emergency leak management and what to expect from your Leak Detection appointment.
Yes, roof leak repair is one of our core services. We handle all types of roof and ceiling leaks to keep your home dry and protected. We specialize in accurately locating the source of roof leaks and providing solutions that last. Unlike roofing contractors, who may recommend a costly full roof replacement that doesn't always resolve the issue, our targeted repairs address the exact problem, which can save you a lot of money.
Yes, we detect and repair all types of basement leaks, ranging from minor wall seepage to major water intrusion. Basement leaks often result from foundation cracks, poor exterior drainage, clogged gutters, or improper soil grading around your house. Watch for musty odors, damp walls, chalky residue on concrete, or puddles after heavy rain.
We break our process down into distinct phases to ensure accuracy and high-quality results:
Initial Leak Detection: This on-site investigation typically takes between 2 to 8 hours.
Comprehensive Reporting: You receive a detailed Leak Report within approximately 14 business days.
Water Intrusion Repair Phase: Average repairs take 1 to 2 days to complete. Extensive structural work might require a couple of weeks.
Weather Testing: After we complete the repairs, we wait for 3 to 4 weather events to pass. This waiting period proves the leak is fully resolved before we perform cosmetic drywall repairs.

We'll likely open a viewable area (cutting a hole in the wall or ceiling) on the interior where your leak is presenting. This allows us to explore how the leak is behaving in order to find the root cause of the leak.
We don’t work directly with your homeowner’s insurance, but we will work with you if you are getting reimbursed. If you need extra time to figure out the details with your insurance or are waiting for a check from them, we can adjust or pause with you to make the process as smooth as possible.
We stand by our expertise. If the exact same leak reappears after our repair, we will return to repeat the Leak Detection process free of charge. If we find any issues with our workmanship, we will correct them for free. If we discover completely new, contributing factors, we will provide a clear estimate for those additional repairs.
