Leak Detection and Repair

Leak Detection and Repair

Home owners, water can be a blessing or curse. When it is nourishing plants, filling the pool for some summer fun, or running from the shower head for an invigorating morning shower, it can be taken for granted. But, when it leaks when it’s not supposed to, it can be at the least a nuisance. At the worst, it can cause damage that can run into the thousands of dollars.

Steps for Detecting and Repairing Leaks

If you know or suspect that there is a water leakage in your home, there are some steps that you can take to protect your property from expensive damage or from simply wasting precious water.

  • If you suspect a leak from the running water, turn off all water faucets and appliances so that no water is running.
  • Next, check your water meter. It will usually be in the basement near the hot water heater or the furnace.
  • Take a look at the water meter’s dial. On newer models, if the small dial on the meter is turning, there is a leak. On older models, if the dial is moving, there is a leak. If the dial is moving slowly, chances are the leak is small. If the dial moves rapidly, you may have a break in your main line.
  • Check for wet areas in your yard or under house.
  • You may want to call the water company for help.
  • Have the leak repaired as soon as possible.
  • Once you have the leak repaired, contact the water company and explain the situation. They may offer to make an adjustment.


If the leaking in your house is due to rain water that is getting in, find the source of the leak as soon as possible. We are specialized in locating hard to find leaks, If it is from the roof, make sure there is no structural damage before the roof is fixed. If the leak is in the basement, apply a waterproofing materials to the outside of the foundation and install sub-surface french-drain in the perimeter of the entire house foundation.

Waterproofing Roofs

Roofs are usually threatened by ice freezing along the peripheries of the building, which dams up rain and forces it to seep between shingles and into flaws. Most roofs possess a felt paper covering beneath the shingles to serve as a barrier against water, but this covering is often inadequate.

An effective supplement is the use of special rubber-based sheets, which, in addition to being watertight themselves, often possess trace specks of glass that help to resist ultraviolet light as well as moisture.

Waterproofing Decks

Decks can often be the most vulnerable structures in any home. No other purely wooden component of a building receives quite so much exposure to the elements, and decks are often seriously damaged by rainwater which settles on the flat surface and gradually soaks into the house structure. Decks should therefore be protected and constructed correctly to divert water away from the interior of your home.

Waterproofing Basements

Basements are frequently difficult to waterproof because the source of the water damage is not always readily apparent. To determine whether moisture is coming from an exterior leak or the condensation of water within the basement itself, one commonly applies a sheet of water-resistant material such as aluminum against the problem wall, sealing it tight and letting it sit for several days, after which one can glean the source of the moisture by noting which side of the sheet is damp. An external leak may be the result of incorrectly slanted landscaping or poorly designed gutters and downspouts and drainage , which direct water towards the basement walls where it seeps in through hair-thin crevices and not existent French drain system.

It is often easiest simply to alter the slope of the ground or the positioning of the gutter and place all down spout water in to a drainage system that carries the water to street level. In severe water intrusion situation a sub-surface French-drain needs to be installed to carry water away from the foundation of the structure depending on the engineering of the foundation system this aspect needs to be designed specifically to fit to your needs. Internal condensation is usually caused by moisture released from plumbing which runs through the basement; this can frequently be addressed by applying additional insulation to the pipes.

If Installation of exterior French drain system is cost prohibitive you may settle for interior perimeter drainage to carry all the water to outside using Sump pumps.

Waterproofing Sidings

Sidings frequently is found to be leaking due to improper water membrane installation or failure. Most of the leaks occur as a result of improper flashing at the windows and door openings, Only a trained water proofing professional truly is able to isolate the problem and solve these issues. We here at Montclair Construction specialize in finding the leaks and terminating them.

 Exterior Drainage

A French drain or land drain is a ditch filled with gravel, rock that redirects surface and ground water away from an area. French drains are common drainage systems, primarily used to prevent ground and surface water from penetrating or damaging building foundations. French drains are also used behind retaining walls to relieve ground water pressure.

A French drain works on the principle of gravity, being slightly sloped down from the area to be drained to the area where one wishes to redirect the water. It is typically lined with perforated clay pipe and surrounded with a landscaping textile to prevent dirt or plant roots from clogging the system. Excess ground and surface water percolates into the French drain and is directed away.

Variations on the French drain model include: 

  • filter drain is to drain ground water
  • collector drain (or inteceptor drain) combines groundwater drainage with the interception of surface water or run-off

French drains can lead to dry wells or environmentally-friendly rain gardens where the extra water is held and absorbed by plants, when city water systems, or other waste water areas can not be used.

4 Steps To Chimney Leak detection and Repair

1. Inspection of the roof – Chimney leak repair should start with a thorough inspection ofyour chimney’s base and walls to evaluate the damage. This will allow yourroofer to proceed with appropriate repair options. In many instances not onlyflashings but siding and evendecking needs to be replaced and your roofer should be able to determine thatduring the inspection.

2. Old material removal – Most often than not, old material at the base of the chimney needs to be removed and new flashing andseals properly installed. This includes removal of old roof cement and waterproof caulking that was applied to seal the flashing/shingle/chimney connection, all flashings, siding and possibly even plywood.

3. Flashing replacement – Step and counter flashing will most likely need to be replaced: any cracks, tears or bending are unacceptable.

4. Sealing – Once new flashing is in place, masonry caulk is used to cover flashing/chimney joints, and flashing seams are sealed with waterproof roofing cement or flashing cement/caulking.
