Siding Repair & Replacement

Siding life expectancy not only depends on the siding material used, but also the care, surrounding climate, and age of the siding. Whatever your situation and no matter how small or large the siding repair project may be, you can trust Sister Siding contractors to be honest and timely with the required repairs. After our initial inspection, we will explain what kind of siding repair and installation service is necessary to fully restore your home’s siding.

Full Siding Replacement

Even with the best materials and maintenance, siding doesn’t last forever. If your siding hasn’t been updated within the last 30 years, it might be time for new siding. Depending on the type of siding used on your home and its condition, a full siding replacement isn’t always required. If your siding only has a few signs of wear, you can go forward with minor siding repairs instead. An exterior siding inspection will clarify if and when a full siding replacement is necessary or not.

In the event that your home or facility does need a total siding restoration, Sister Siding can remove the old siding and install new walls for a full siding replacement. Renewing your siding will update the look of your building and also give it added protection against weather and pests while improving structure insulation for better energy efficiency.

Siding Repair & Replacement For Gaps, Cracks & Holes

Has your siding been attacked by external elements? Storms in the Pacific Northwest can present wind, rain, and hail, which are all able to damage siding with holes and gaps. High heat temperatures can also cause certain siding materials to bend and crack. Likewise, pests can also create holes and gaps in siding. All of these issues can lead to large insulation issues and water damages which can lead to larger issues if left untreated.

Contact us to repair siding cracks, siding holes, and gapping before the issue escalates to something worse and more costly. Have a different type of siding repair need? Tell us about the issue and we’ll let you know what we can do to help keep your home, or other structure, safe.

Siding Rot Repair & Replacement

Both dry and wet rot are forms of fungal decay that permeate wooden structures exposed to water damage. The main difference between the two types of rot is that dry rot spreads while wet rot festers where the moisture is located. Wood rot can destroy an entire building when left untreated for a long period of time. Depending on the severity of the issue, the rot may also be dangerous to your health. Constant moisture is unavoidable in the Pacific Northwest, so if you suspect water damage in your home, it’s wise to have the problem resolved before it becomes a more costly project in the future.

Sister Siding installers will not only treat the rot so it doesn’t return, but also remove old siding in the area and replace it with new siding panels for added protection. If you would like us to do an inspection of your home for suspected wood rot or moisture damage, contact us to get started. *contact button*

This type of siding material is pest resistant, fire resistant, moisture resistant, and rot resistant.

Sister Siding’s Preferred Siding Materials

Fiber Cement Siding

Sister Siding wants to ensure a quality result with every siding installation and repair. This is why we use fiber cement as our primary material for siding solutions. Fiber Cement is the top material used to side houses in the United States. It is a composite mixture of water, sand, and cellulose wood fibers. The final product is designed to mimic wood and you can mold it into any pattern, as well as paint or have it finished to your liking. One of the main reasons Sister Siding uses fiber cement as a preferred siding material is because of it’s quality and durability. Fiber cement is able to withstand extreme weather elements, as well as being moisture resistant, non-flammable, and low maintenance, it is also resistant to all kinds of pests and insulation issues. It is the best siding material for homes and other buildings in the Pacific Northwest that are often exposed to wind and rain.

What Brand Of Siding Does Sister Siding Use?

Sister Siding uses Hardie Plank Fiber Cement Siding and Allura Fiber Cement Siding for siding repair and replacement projects. James Hardie siding is one of the most well known siding brands in America, due to it’s outstanding performance and design options. Similar to Hardie Plank, Allura siding is both durable and offers a variety of siding design options for every home. Sister Siding only uses the best quality products for siding installations so customers are satisfied with our work and left with siding that lasts.

What Is A Moisture Inspection?

Using a non-invasive moisture meter, Sister Siding can test the surface of your siding to see what level of moisture is or isn’t behind its outer layer.

What Is A Water Seal Inspection?

Sister Siding will inspect all caulking as well as roof kick-out flashings, roof fascia flashings, z-flashings and butt-joint flashings to ensure that the home is properly water sealed.

Why Is A Moisture & Water Seal Inspection Necessary?

After each inspection, Sister Siding will give recommendations to the building owner based on what was found so that no surprise water damages creep up during the siding installation.

“Our siding had a good amount of dry rot and panels which were deteriorating over the years. Lucas came by for an estimate and was very helpful in talking through what did and didn’t need to be done. We were selling our house, and this was part of the repairs to finalize our sale. Lucas got us on the schedule quickly to keep our pending sale moving. Work looks great!”
