2. Ignoring Moisture Protection

Siding is not the only thing protecting the outside walls.

Weather resistant barriers, flashing and sealed openings are an important component of the overall exterior system. In addition to seam edges and panel joints, the window and door installation areas, corners and other opening must be given special attention.

Improper installation of or failing to install moisture-protection members can result in water having direct access to the wall system and cause it to decay.

3. Using Incorrect Measurements

Precise measurements are vital during a siding installation. Getting too little siding material can set back the schedule, whereas getting too much can add to scrap and product costs.

Consider fenestration, doors, corners, rooflines and other architectural features.

Fastening and spacing are critical in proper installation of any kind of residential or industrial cladding. Fast a slip-into-place, allowing siding to flex and flex with winds while remaining firm attached to the exterior wall.

5. Neglecting Expansion and Contraction

Siding materials are affected by temperature variation and will expand and contract. This is a typical occurrence but the installation has to allow for this movement.

Corner wraps, windows, doors, and other fixtures. If you don't give a little in these areas, you're creating pressure on your siding.

On occasion, lack of room could result in warping, cracking, or visible gaps. Appropriately spaced siding will hold up well and give the appearance of being more uniform as temperatures change.

6. Installing Over Damaged Walls

Putting new siding on damaged walls won't help if the walls are in poor shape in the first place.

A professional can assess what needs to be addressed prior to installation. Fixing root issues can contribute to a more solid base for the new exterior.

7. Choosing Materials Based Only on Appearance

Siding decisions are frequently made on the basis of color, texture and appearance. However, in addition to visual qualities, material performance is an important consideration.

Several materials used for siding are made to handle specific weather and installation requirements.

May: The first phase of planning involves choosing the right product based on your property design, weather conditions, maintenance requirements and how much money you want to put into the project.

A professional can describe the qualities of any of the materials and provide advice to help homeowners understand exactly what that process entails.

8. Overlooking Flashing Around Openings

Siding, windows, doors, vents and other penetrations all need precise installation as they can all act as a water path.

Failure to flash correctly or seal transitions can permit water to penetrate behind the siding.

Proper spacing in these areas must be maintained, and materials must be installed in a manner that will shed water down and away from the wall.

9. Forgetting About Trim and Finishing Details

Trim is a key component of any siding project as it helps create a clean transition around windows, doors, corners, and other areas.

Gaps and uneven finishes can be the result of ill-fitting trim work.

Allow for time to install trim properly in order to achieve cleaner lines and added protection around sensitive locations.

10. Attempting Complex Installation Without Proper Experience
