Is the reward for repairing mosques the same as the reward for building them?

Praise be to
Allaah.

This question was put to Shaykh
Muhammad ibn ‘Uthaymeen (may Allaah have mercy on him), and he said: 

Repairing mosques comes under
three categories: 

1.                
Cosmetic renovations for which there is no need. In this case
there is the fear that the one who undertakes this task may be nearer
to sin than to being safe from it, because if there is no need for it
and the purpose is, rather, to beautify the mosque, then it is a waste
of money with no benefit. The money which was spent on these renovations
could have been spent on other mosques which the people could have benefitted
from.

2.                
Renovations which are needed but not essential, such as when
floor tiles or plaster are cracked, but the mosque is standing. 
A person will be rewarded for this, because it is like cleaning the
mosque, and the Prophet

(peace and blessings of Allaah be upon him) commanded us to build mosques
among the houses and to clean and perfume them.

3.                
Repairs which are essential, such as when there are cracks in
the walls of the mosque or in the beams of mosques built of reinforced
concrete, and the like. This comes under the same ruling as building
because these repairs are essential.
