Building today For a Stronger Tomorrow

Our restoration team can assess deterioration, predict future damage, and develop remedial repair solutions to extend the life of the building element, ensure safety, and improve aesthetics.

Our industry-leading knowledge of construction materials, durability and sustainability contributes significantly to restoration projects.

Each restoration project is unique. Our team works closely with the owner and contractor to develop a strategy that meets each project’ 5 challenges, from cost effectiveness and timing to creative solutions and minimizing disruption of operating facilities. We ensure high quality restoration as our prime objective.

Our work covers building envelope systems, which includes:

◙ Window/Door Replacement
◙ Masonry Repairs
◙ Caulking Repair & Replacement
◙ Architectural Coatings
◙ EIFS – New Installations & Repairs
◙ Metal Siding – New Installation & Repairs

ElFS is an insulating, decorative and protective finish system for exterior walls that can be installed on any type of construction, both on newly constructed or existing buildings. It is the only exterior wall covering that insulates and provides weather protection in a selection of shapes, colours and textures that can replicate almost any architectural style or finish material or stand by itself as an architectural finish.

At Durmus we are highly acclaimed in the EIFS industry for our innovative approach, we have helped many customers reduce cost and structural requirements and increase energy efficiency by offering EIFS alternative to other cladding types like Brick, Blocks, Limestones, Metal Panels and even wood sidings and panels, we have developed an exceptional level of artistry and mastery in simulating almost any cladding or finish type with EIFS.

Durmus Group Inc. is recognized as one of the top ElFS installers in the construction industry today. We are certified to install all well-recognized ElFS manufacturers' products, and our installation experience includes many projects located throughout Ontario and other parts of Canada.

Joint sealants are used to seal joints and openings between two or more substrates, and are a critical component for building construction and design. The main purpose of sealants is to prevent air, water, and other environmental elements from entering or exiting a structure while permitting limited movement of the substrates.

When joints fail, leaks and damage to buildings follow. Sealants can help ensure that your buildings stay tight and dry Modern residential and commercial structures rely heavily on sealants to prevent water damage to buildings and their contents.

When mortar joints are hit by wind and moisture, they start to disintegrate. Loose mortar is washed away, and the mortar continues to wear. Eventually, the masonry units being held into place become loose and fall out.

Tuck-pointing is a common maintenance repair for masonry walls. It involves filling in eroded or weathered mortar joints between masonry units with new mortar material. Prior to tuck-pointing, the existing mortar joints should be properly ground (routed) to provide a clean substrate for the new mortar to adhere to.

Tuck-pointing is often necessary to restore the integrity of the mortar due to normal weathering and aging of a masonry building; however, the need for tuck-pointing often indicates more significant problems, such as a movement or shift in the vertical or horizontal plane of the wall. Even the well-built masonry walls require occasional repairs. Mortar joints that are exposed to the weather typically need to be tuck-pointed every 30 years or so.

Durmus’s recommendation for a long lasting tuck-pointing job is to grind and chisel out all the joints If your grout lines are generally worn and cracking, you need to tuck-point the entire area or the problem will worsen rapidly.

We use only grinding tools with a vacuum attachment that provide dust removal at a rate of 9500 or more. That means the tools meet Underwriters Laboratory’s (ULC) and OSHA’s requirements for a clean, safe work area.

Parapets are the portion of exterior walls that extend above roof level. They are exposed to the weather on both faces, and, thus, are often prone to accelerated weathering and deterioration. It is not uncommon to see parapets that are not properly secured to the roof structure and have deflected out of plane. Parapets that lean toward or away from the building should be evaluated in detail. Without proper maintenance and necessary repairs, severely distressed parapets could eventually collapse.

Depending upon the severity of the deterioration, repairs of parapets can range from tuck-pointing of the mortar joints to providing additional back bracing to the roof structure. In the most severe cases, it may be necessary to completely rebuild the parapet wall with steel reinforcing bars dowelled into the structure below the roof line.

Lintels support the masonry over openings in a wall, such as at doors or windows. Lintels are generally constructed of steel angles, channels, wide flange beams, or reinforced masonry bond beams.

Steel lintels are susceptible to corrosion through repeated cyclical exposure to moisture. The corroded steel can expand by up to 10 times its thickness. This corrosion and expansion of the steel exerts tremendous force on the adjacent masonry, which causes movement and eventual cracking in the wall. Severely corroded lintels may require complete removal and replacement with new galvanized steel members.

Efflorescence is the presence of salt residue leeching from within the masonry material that forms on the exterior surface of the wall. It is generally caused when a large amount of water within the wall filters out through the face of the wall. Efflorescence may be unsightly, but it is not typically indicative of a structural problem; however, the presence of residue is a symptom of a potential problem. This excessive moisture may cause weakening of the mortar joints and may eventually deteriorate the masonry units.

It is difficult to stop water infiltration until the actual source is identified, so it is important to understand the root cause of efflorescence. A common method of tracing sources of water infiltration involves water testing, along with a review of original building drawings and targeted inspection openings. Once the source of water infiltration is determined, a plan for the design of the wall repairs can begin. Repairs can range from tuck-pointing to installation of a properly designed thru-wall flashing system. In severe cases, it may be necessary to reconstruct a portion of the distressed area.

Water penetration into interior spaces may result from errors in design and/or construction of the wall drainage system. In most cases, leaks can easily be avoided if the designer properly details the flashing and weep system and carefully monitors construction for quality workmanship and conformance with design.

The Building Evaluation Report by Durmus Group Inc. provides a complete and thorough visual inspection of all buildings’ exterior and interior. Our evaluation includes mortar condition, flashings, and caulking.

Building structures require ongoing maintenance to prevent them from falling into disrepair as a result of the ravages of time and use.

In our experience, we have learned that not all repairs are l visible by walking around a building. In some cases, we may recommend an investigative opening.

If we see signs of possible underlying issues, we will recommend opening an investigation. This will help us give you the most accurate quote possible and help eliminate the surprise of unforeseen issues after the project has started.
