That depends on it concentration. 1 mole per liter NaOH (=40g/l) has a pH value of 14. 0.1 mole per liter has a pH of 13; 0.01 mole per liter gives pH=12, ...
-log(10^-4 M NaOH) = 4 14 - 4 = 10 pH NaOH -----------------------

As NaOH is a strong base I would not be surprised to see a 14 pH at least.
The pH value for this solution is 13.
Sodium hydroxide, NaOH, has a very high pH, so it can be used to raise the pH of some mixture that is too acidic.
Sodium Hydroxide NaOH
You dont - adding NaOH increases pH.
1 millimolar = 0.001 M NaOH ( a base, remember ) - log(0.001 M NaOH) = 3 14 - 3 = 11 pH ----------
-log(10^-4 M NaOH) = 4 14 - 4 = 10 pH NaOH -----------------------

HCl : makes it acidic. it decreases the pH NaOH : makes it alkaline. it increases the pH

Supposed the acid and base are both strong: pH of the acid is 0.0 and the pH of the base (hydroxide) is 14.0
pH depends on concentration. Strong bases are for example: NaOH KOH Ca(OH)2 http://en.wikipedia.org/wiki/Base_(chemistry)
A 0.01 M solution of NaOH has a pH =13
