Some industry publishers dub fiber cement as a '100 yr product' and then there really should exist no need to ever have to repair it right? The truth is at that place is e'er variables with any home product that could crave repair down the line, more often than not having to do with faulty installation (gaps, uneven, loose from poor nailing, lack of backer flashing) but could also include rodents, collisions, farthermost conditions, or water damage to the underlayment.
The damage will have to exist analyzed to see if information technology can be a corrective fix or if the boards demand to be replaced altogether.
Understanding How Fiber Cement is Installed
Removing fiber cement boards from the outside of a habitation is basically installing in reverse. Therefore information technology'due south important to know how the product is installed to begin with. Fiber cement lap siding is generally bullheaded-nailed at the top of the plank with the nails being covered past the subsequent row of siding.
Removing a Damaged Board
In order to remove the board yous'll have to pull out or cut off the nails, which are likely located underneath the overlapping siding on the row above. Utilize a pry bar and lift the bottom edge of the overlapping siding gently every bit to not cause any additional damage. As yous pry, utilize woods shims to create a buffer between the overlapping piece and the damaged piece so that nails can be removed from the damaged piece easier.
Replacing With the New Board
If the reason the damaged board needed to be removed was because of abiding water exposure, y'all'll need to audit the underlayment and backer board behind the siding to brand sure it too hasn't rotted or go vulnerable. At that place's no sense in making repairs until any issues have been alleviated. If multiple rows of siding had to be removed always piece of work from the lesser up when installing the replacement pieces.
Check the 'reveal' or exposed areas on other sections of the habitation to know how much space to exit when installing replacement boards – using a chalk line if needed to make certain this stays consequent from end to stop. When sliding the final board into place underneath an overlapping row of siding, you may take to face smash it into identify because the summit nailing lip is hard to reach. Use some affect up paint to cover up these face up nails and and then re-caulk any gaps to completely repair fiber cement lap siding.

The patch is mixed, formed, and spread to match the contours of the lath. You so let the patch dry and sand it to blend into the surrounding parts of the plank. Finally, paint the area and although the patch may not be cosmetically perfect information technology blocks out water and insect access.
How to Repair Loose Fiber Cement Siding
There are two main reasons that cause fiber cement siding to come loose, both of which stalk from faulty installation of either missing a stud or nailing likewise high on the pieces. A plank that is nailed too loftier will offset to sag because the sparse top lip has started to give. This tin can be diagnosed by a lot of vertical movement in the board.
Planks that have been nailed missing the stud volition commencement to pull away from the business firm. Either way, the simplest gear up is to face up blast the boards dorsum into identify, this time hitting the stud. If there is no stud bachelor (such every bit near gable trim) and the plank is curling or rattling, information technology's recommended to 'pivot back' the board by face nailing it 3/4" to 1" from the bottom – strictly for aesthetics and non to increase air current load. Caulk can also exist used to secure an angled cut or another section where a backer is not available.
Understanding Dealing With Fiber Cement Gaps
One matter to notation virtually gaps between joints of fiber cement siding is that they are left in that location on purpose. Although the material expands and contracts less than wood, best installation practices even so permit for some movement and to respond to shifts in the abode.
Edge gaps are filled with caulk to foreclose h2o damage and every siding butt joint should have flashing backside it to do the same. The flashing should exist a non-discreet color then that information technology is barely noticeable. If at that place are significant gaps that are destroying the aesthetics of the siding (board likewise small-scale to begin with, likewise large of expansion gaps) the all-time practice is to remove and replace, both for cosmetics and moisture prevention.
Fiber cement siding is a highly durable product but anything installed 30-40 years on the exterior of a habitation is going to be vulnerable to impairment at some signal. Luckily, another versatile benefit of this product is that fixes are usually easy and generally inexpensive.
Just remember to always eliminate the underlying problem (water damage, rodent infestation, delaminated boards, etc.) earlier making repairs as you'll but be running around in circles.

In the back of my home the everyman line of fiber cement siding has come down in a few spots and I need it repaired. It appears that the layer on the dwelling house under the siding is some sort of particle board which I am sure needs to be replaced. There is no water barrier material at all!
I was quoted a cost of $250 for a contractor to come out and view the damage. Repair costs would be deducted from the $250. The cost seems high to me since it is ten feet of siding which needs repair. What practise you think about the pricing?
Keep up the nifty work!
